[0039] The technical terms in this specification refer to the customary terms in the technical field. If some terms are explained or defined in this specification, the interpretation of these terms shall be based on the explanation or definition in this specification. Each embodiment of the present disclosure has one or more technical features. Under the premise of possible implementation, those skilled in the art may selectively implement some or all of the technical features in any embodiment, or selectively combine some or all of the technical features in these embodiments.

[0040] In the various embodiments listed below, the same reference numerals will be used to represent the same or similar components or elements.

[0041] Figure 1A FIG. 1 is a schematic diagram of an electric energy distribution system according to an embodiment of the present disclosure. Figure 1B Schematic diagram of an electric energy distribution system according to another embodiment of the present disclosure. In this embodiment, the electric energy distribution system 100 is a parallel type electric energy distribution and supply system, which can be applied to DC-DC converters, DC-AC converters, AC-DC converters, and AC-AC converters, but the embodiments of the present disclosure are not limited thereto. Please refer to Figure 1A or Figure 1B The power distribution system 100 includes a first power module 110 and a second power module 120. The first power module 110 is provided with a first impedance component 111. The second power module 120 is provided with a second impedance component 121.

[0042] In some embodiments, as Figure 1A As shown, the first impedance component 111 and the second impedance component 121 are respectively variable impedance components or digital variable impedance components, but the embodiments of the present disclosure are not limited thereto. Figure 1A As shown, the first impedance component 111 and the second impedance component 121 can be set in a virtual manner, for example, by executing a software, but the embodiments of the present disclosure are not limited thereto. Figure 1B As shown, the first impedance component 111 and the second impedance component 121 include resistors, capacitors or inductors respectively, but the embodiments of the present disclosure are not limited thereto. In some embodiments, as shown in FIG. Figure 1B As shown, the first impedance component 111 and the second impedance component 121 are fixed impedance components or semi-fixed impedance components, respectively, but the embodiments of the present disclosure are not limited thereto.

[0043] In this embodiment, the second power module 120 and the first power module 110 may have different specifications. For example, in some embodiments, the first power module 110 and the second power module 120 may be of different brands and have different power levels. In some embodiments, the first power module 110 and the second power module 120 may be of the same brand and have different power levels. Alternatively, the first power module 110 and the second power module 120 may be batteries (e.g., decommissioned batteries), power supplies, or other suitable power supply devices, but the disclosed embodiments are not limited thereto.

[0044] In this embodiment, the impedance value of the first impedance component 111 can match the power of the first power module 110. For example, when the power or power provided by the first power module 110 is 6 kW or 6 kWh, the impedance value of the first impedance component 111 is, for example, 6. For example, when the power or power provided by the first power module 110 is 4 kW or 4 kWh, the impedance value of the first impedance component 111 is, for example, 4. The remaining methods for matching the impedance value of the first impedance component 111 with the power of the first power module 110 are similar.

[0045] Furthermore, the impedance value of the second impedance component 121 can be matched to the power of the second power module 120. For example, when the power or power provided by the second power module 120 is 5 kW or 5 kWh, the impedance value of the second impedance component 121 can be, for example, 5. For example, when the power or power provided by the second power module 120 is 2 kW or 2 kWh, the impedance value of the second impedance component 121 can be, for example, 2. The same applies to matching the impedance value of the second impedance component 121 with the power of the second power module 120.

[0046] In this embodiment, the first power module 110 can provide the first power according to the first power distribution information corresponding to the first impedance component 111, and the second power module 120 can provide the second power according to the second power distribution information corresponding to the second impedance component 121. Further, the first power module 110 is connected in parallel with the second power module 120, and the first impedance component 111 is connected in series with the second impedance component 121. In addition, the end of the first impedance component 111 that is not connected to the second impedance component 121 can, for example, receive a voltage source control signal VS provided by an external device, and the end of the second impedance component 121 that is not connected to the first impedance component 111 is, for example, connected to a ground terminal. In this embodiment, the external device is, for example, a voltage source, but the embodiments of the present disclosure are not limited thereto.

[0047] During operation of the power distribution system 100, an external device may provide a voltage source control signal VS to the first impedance element 111 of the first power module 110. The first impedance element 111 and the second impedance element 121 may then generate first power distribution information and second power distribution information, respectively, based on the voltage source control signal VS.

[0048] For example, assuming the first power module 110 can provide 6 kWh of power, the corresponding impedance value of the first impedance element 111 is 6, and the second power module 120 can provide 4 kWh of power, the corresponding impedance value of the second impedance element 121 is 4. Assuming the load power demand is 6 kWh, according to the current impedance value settings, the first power module 110 needs to provide 60% of the power (100% * 6 / (6 + 4)), that is, 6 kWh * 60% = 3.6 kWh, and the second power module 120 needs to provide 40% of the power (100% * 4 / (6 + 4)), that is, 6 kWh * 40% = 2.4 kWh. At this time, based on the load power demand of 6 kWh, the voltage source control signal VS is generated to be 6V. With the series connection of the first impedance element 111 and the second impedance element 121, the voltage source control signal VS is divided to generate the first power distribution information and the second power distribution information. The first power distribution information is, for example, (voltage source control signal VS*(impedance value of the first impedance component 111) / (impedance value of the first impedance component 111+impedance value of the second impedance component 121), that is, 6*(6 / (6+4))=3.6). The second power distribution information is, for example, (voltage source control signal VS*(impedance value of the second impedance component 121) / (impedance value of the first impedance component 111+impedance value of the second impedance component 121), that is, 6*(4 / (6+4))=2.4.

[0049] Then, the first power module 110 can generate a first power corresponding to 3.6kWh based on the first power distribution information (for example, 3.6) corresponding to the first impedance component 111, and the second power module 120 can generate a second power corresponding to 2.4kWh based on the second power distribution information (for example, 2.4) corresponding to the second impedance component 121. Therefore, the power distribution system 100 can provide 6kWh of power, that is, 3.6kWh plus 2.4kWh. Since the power distribution system 100 only needs to generate power according to load demand, the power supply specifications of the power distribution system 100 are not restricted. The power distribution can have mixed power supplies of different specifications, and provide corresponding power through the power distribution information corresponding to the impedance component set by the power module, which can effectively reduce the complexity of circuit design and increase convenience in use.

[0050] like Figure 1AAs shown, the first impedance component 111 and the second impedance component 121 are configured, for example, in the form of variable impedance components or digital variable impedance components. When the first power module 110 and the second power module 120 are normal, the first impedance component 111 and the second impedance component 121 (for example, configured in the form of variable resistors) are controlled to not be short-circuited. Then, the first impedance component 111 and the second impedance component 121 can process the voltage source control signal VS using a voltage division method according to the above embodiment to generate first power distribution information and second power distribution information. Subsequently, the first power module 110 can provide the first power according to the first power distribution information, and the second power module 120 can provide the second power according to the second power distribution information.

[0051] In addition, when the first power module 110 or the second power module 120 fails, the first impedance component 111 or the second impedance component 121 can be controlled to be short-circuited, and the first power module 110 or the second power module 120 can then provide corresponding power again.

[0052] For example, when the second power module 120 fails, since the load demand is still 6kWh, the first power module 110 is changed to provide 100% of the electrical energy (100%*6 / (6+0)), that is, 6kWh*100%=6kWh. The first impedance component 111 can re-obtain the first electrical energy distribution information according to the voltage source control signal VS, for example, 6*(6 / (6+0))=6. Then, the first power module 110 can generate the first electrical energy corresponding to 6kWh according to the re-obtained first electrical energy distribution information (for example, 6). In this way, even if a fault occurs, the impedance component configured for the faulty power module is short-circuited, and the normal power module provides the corresponding electrical energy according to the corresponding electrical energy distribution information re-obtained by its impedance component, thereby increasing the convenience of use.

[0053] In addition, if Figure 1B As shown, the power distribution system 100 further includes a first switch component 112 and a second switch component 122. The first switch component 112 is connected in parallel with the first impedance component 111. The second switch component 122 is connected in parallel with the second impedance component 121. When the first power module 110 and the second power module 120 are normal, the first switch component 112 and the second switch component 122 are controlled to be non-conductive, and the first impedance component 111 and the second impedance component 121 can process the voltage source control signal VS by voltage division according to the above embodiment to generate first power distribution information and second power distribution information. Then, the first power module 110 can provide the first power according to the first power distribution information, and the second power module 120 can provide the second power according to the second power distribution information.

[0054] Furthermore, when a fault occurs in the first power module 110 or the second power module 120, the first switch component 112 or the second switch component 122 is controlled to be turned on, thereby short-circuiting the first impedance component 111 or the second impedance component 121. At this point, the first power module 110 or the second power module 120 can resume providing the corresponding power.

[0055] For example, when the second power module 120 fails, since the load demand is still 6kWh, the first power module 110 is changed to provide 100% of the electrical energy (100%*6 / (6+0)), that is, 6kWh*100%=6kWh. The first impedance component 111 can re-obtain the first electrical energy distribution information according to the voltage source control signal VS, for example, 6*(6 / (6+0))=6. Then, the first power module 110 can generate the first electrical energy corresponding to 6kWh according to the re-obtained first electrical energy distribution information (for example, 6). In this way, even if a fault occurs, the impedance component configured for the faulty power module is short-circuited, and the normal power module provides the corresponding electrical energy according to the corresponding electrical energy distribution information re-obtained by its impedance component, thereby increasing the convenience of use.

[0056] In some embodiments, as Figure 1B As shown, when the first impedance component 111 and the second impedance component 121 are physical components, the first switch component 112 and the second switch component 122 can also be physical components, but the embodiments of the present disclosure are not limited thereto. In some embodiments, as Figure 1B As shown, when the first impedance component 111 and the second impedance component 121 are set in a virtual manner, the first switch component 112 and the second switch component 122 can also be set in a virtual manner, but the embodiments of the present disclosure are not limited thereto.

[0057] In the above embodiment, the power distribution system 100 includes two power modules, namely, a first power module 110 and a second power module 120. However, the disclosed embodiments are not limited thereto. The number of power modules may be three or more, and each power module is provided with a corresponding impedance component. Each power module can provide corresponding power based on the power distribution information corresponding to its impedance component. The operation of three or more power modules can refer to the description of the above embodiment and will not be further described here.

[0058] Figure 2A FIG. 4 is a schematic diagram of an electric energy distribution system according to another embodiment of the present disclosure. Figure 2BSchematic diagram of an electric energy distribution system according to another embodiment of the present disclosure. In this embodiment, the electric energy distribution system 200 is a series type electric energy distribution and supply system, which can be applied to DC-DC converters, DC-AC converters, AC-DC converters, and AC-AC converters, but the embodiments of the present disclosure are not limited thereto. Please refer to Figure 2A or Figure 2B The power distribution system 200 includes a first power module 210 and a second power module 220. The first power module 210 is provided with a first impedance component 211. The second power module 220 is provided with a second impedance component 221.

[0059] In some embodiments, as Figure 2A As shown, the first impedance component 211 and the second impedance component 221 are respectively variable impedance components or digital variable impedance components, but the embodiments of the present disclosure are not limited thereto. Figure 2A As shown, the first impedance component 211 and the second impedance component 221 can be set in a virtual manner, for example, by executing a software, but the embodiments of the present disclosure are not limited thereto. In some embodiments, as Figure 2B As shown, the first impedance component 211 and the second impedance component 221 include resistors, capacitors or inductors respectively, but the embodiments of the present disclosure are not limited thereto. In some embodiments, as shown in FIG. Figure 2B As shown, the first impedance component 211 and the second impedance component 221 are fixed impedance components or semi-fixed impedance components, respectively, but the embodiment of the present disclosure is not limited thereto.

[0060] In this embodiment, the second power module 220 and the first power module 210 may have different specifications. For example, in some embodiments, the first power module 210 and the second power module 220 may be of different brands and have different power levels. In some embodiments, the first power module 210 and the second power module 220 may be of the same brand and have different power levels. Alternatively, the first power module 210 and the second power module 220 may be batteries (e.g., decommissioned batteries), power supplies, or other suitable power supply devices, but the disclosed embodiments are not limited thereto.

[0061] In this embodiment, the first impedance component 211 refers to admittance, which is the reciprocal of impedance and is essentially still resistance, capacitance or inductance. The admittance value of the first impedance component 211 can match the electrical energy of the first power module 210. For example, when the power or electrical energy that the first power module 210 can provide is 6kW or 6kWh, the admittance value of the first impedance component 211 is, for example, 6. For example, when the power or electrical energy that the first power module 210 can provide is 4kW or 4kWh, the admittance value of the first impedance component 211 is, for example, 4. The manner in which the admittance values ​​of the remaining first impedance components 211 are matched with the electrical energy of the first power module 210 can be inferred by analogy.

[0062] In addition, the second impedance component 221 of this embodiment is referred to as the admittance component, just like the first impedance component 211. The admittance value of the second impedance component 221 can be matched with the power of the second power module 220. For example, when the power or power provided by the second power module 220 is 5kW or 5kWh, the admittance value of the second impedance component 221 is, for example, 5. For example, when the power or power provided by the second power module 220 is 2kW or 2kWh, the admittance value of the second impedance component 221 is, for example, 2. The same applies to the matching of the admittance value of the second impedance component 221 with the power of the second power module 220.

[0063] In this embodiment, the first power module 210 can provide the first power according to the first power distribution information corresponding to the first impedance component 211, and the second power module 220 can provide the second power according to the second power distribution information corresponding to the second impedance component 221. Further, the first power module 210 and the second power module 220 are connected in series, and the first impedance component 211 and the second impedance component 221 are connected in parallel. In addition, one end of the first impedance component 211 and the second impedance component 221 can receive a current source control signal CS provided by an external device, and the other end of the first impedance component 211 and the second impedance component 221 can be connected to a ground terminal, for example. In this embodiment, the external device is, for example, a current source, but the embodiments of the present disclosure are not limited thereto.

[0064] During operation of the power distribution system 200, an external device may provide a current source control signal CS to the first impedance element 211 of the first power module 210 and the second impedance element 221 of the second power module 220. The first impedance element 211 and the second impedance element 221 may then generate first power distribution information and second power distribution information, respectively, based on the current source control signal CS.

[0065] For example, assuming the first power module 210 can provide 6 kWh of power, the corresponding admittance value of the first impedance element 211 is 6, and the second power module 220 can provide 4 kWh of power, the corresponding admittance value of the second impedance element 221 is 4. Assuming the load power demand is 6 kWh, according to the current admittance value settings, the first power module 210 needs to provide 60% of the power (100% * 6 / (6 + 4)), that is, 6 kWh * 60% = 3.6 kWh, and the second power module 220 needs to provide 40% of the power (100% * 4 / (6 + 4)), that is, 6 kWh * 40% = 2.4 kWh. In this case, based on the load power demand of 6 kWh, the current source control signal CS is generated to be 6 A. Combined with the parallel configuration of the first impedance element 211 and the second impedance element 221, the current source control signal CS is split to generate the first power distribution information and the second power distribution information. The first power distribution information is, for example, (current source control signal CS*(admittance value of the first impedance component 211) / (admittance value of the first impedance component 211+admittance value of the second impedance component 221), that is, 6*(6 / (6+4))=3.6). The second power distribution information is, for example, (current source control signal CS*(admittance value of the second impedance component 221) / (admittance value of the first impedance component 211+admittance value of the second impedance component 221), that is, 6*(4 / (6+4))=2.4.

[0066] Then, the first power module 210 can generate a first power corresponding to 3.6 kWh based on the first power distribution information (e.g., 3.6) corresponding to the first impedance component 211, and the second power module 220 can generate a second power corresponding to 2.4 kWh based on the second power distribution information (e.g., 2.4) corresponding to the second impedance component 221. Since the power distribution system 200 only needs to generate power according to load demand, the power supply specifications of the power distribution system 200 are not limited. The power distribution can have a mixed power supply with different specifications, and the corresponding power is provided by the power distribution information corresponding to the impedance component set in the power module, which can effectively reduce the complexity of the circuit design and increase the convenience of use.

[0067] like Figure 2AAs shown, the first impedance component 211 and the second impedance component 221 are configured, for example, as variable impedance components or digital variable impedance components. When the first power module 210 and the second power module 220 are normal, the first impedance component 211 and the second impedance component 221 are controlled to not be open-circuited. Then, the first impedance component 211 and the second impedance component 221 can process the current source control signal CS using a shunt method according to the above embodiment to generate first power distribution information and second power distribution information. Subsequently, the first power module 210 can provide the first power according to the first power distribution information, and the second power module 220 can provide the second power according to the second power distribution information.

[0068] In addition, when the first power module 210 or the second power module 220 fails, the first impedance component 211 or the second impedance component 221 can be controlled to be open circuited, so that the first power module 210 or the second power module 220 can provide corresponding power again.

[0069] For example, when the second power module 220 fails, since the load demand is still 6kWh, the first power module 210 is changed to provide 100% of the electrical energy (100%*6 / (6+0)), that is, 6kWh*100%=6kWh. The first impedance component 211 can re-obtain the first electrical energy distribution information according to the current source control signal CS, for example, 6*(6 / (6+0))=6. Then, the first power module 210 can generate the first electrical energy corresponding to 6kWh according to the re-obtained first electrical energy distribution information (for example, 6). In this way, even if a failure occurs, the impedance component configured for the failed power module is opened, so that the second power module 220 does not output energy. In this embodiment, in order to maintain the operation of the power distribution system 200, the failed power module is usually changed to maintain the circuit connection through an internal diode or an external current path. In addition, it is also convenient to remove the second power module 220 for maintenance. Therefore, a normal power module re-obtains corresponding power distribution information according to its impedance component and provides corresponding power, thereby increasing convenience in use.

[0070] In addition, if Figure 2B As shown, the power distribution system 200 further includes a first switch component 212 and a second switch component 222. The first switch component 212 is connected in series with the first impedance component 211, that is, the first switch component 212 is connected between the first impedance component 211 and the ground. The second switch component 222 is connected in series with the second impedance component 221, that is, the second switch component 222 is connected between the second impedance component 221 and the ground.

[0071] When the first power module 210 and the second power module 220 are normal, the first switch element 212 and the second switch element 222 are controlled to be conductive. Then, the first impedance element 211 and the second impedance element 211 can process the current source control signal CS using a shunt method according to the above embodiment to generate first power distribution information and second power distribution information. Then, the first power module 210 can provide the first power according to the first power distribution information, and the second power module 220 can provide the second power according to the second power distribution information.

[0072] Furthermore, when the first power module 210 or the second power module 220 fails, the first switch element 212 or the second switch element 222 is controlled to be non-conductive, causing the first impedance element 211 or the second impedance element 221 to open. At this point, the first power module 210 or the second power module 220 can resume providing the corresponding power. For example, when the second power module 220 fails, since the load power demand remains at 6 kWh, the first power module 210 is now required to provide 100% power (100% * 6 / (6 + 0)), i.e., 6 kWh * 100% = 6 kWh. The first impedance element 211 can re-obtain the first power allocation information (e.g., 6 * (6 / (6 + 0)) = 6) based on the current source control signal CS. Subsequently, the first power module 210 can generate the corresponding 6 kWh of second power based on the re-obtained first power allocation information (e.g., 6). In this way, even if a fault occurs, the impedance component configured for the faulty power module is opened, and the normal power module re-obtains the corresponding power distribution information according to its impedance component to provide corresponding power, thereby increasing convenience in use.

[0073] In some embodiments, as Figure 2B As shown, when the first impedance component 211 and the second impedance component 221 are physical components, the first switch component 212 and the second switch component 222 can also be physical components, but the embodiments of the present disclosure are not limited thereto. In some embodiments, as Figure 2B As shown, when the first impedance component 211 and the second impedance component 221 are set in a virtual manner, the first switch component 212 and the second switch component 222 can also be set in a virtual manner, but the embodiments of the present disclosure are not limited thereto.

[0074] In the above embodiment, the power distribution system 200 includes two power modules, namely, a first power module 210 and a second power module 220. However, the present disclosure is not limited thereto. The number of power modules may be three or more, and each power module is provided with a corresponding impedance component. Each power module can provide corresponding power based on the power distribution information corresponding to its impedance component. The operation of three or more power modules can refer to the description of the above embodiment and will not be further described here.

[0075] Figure 3A FIG. 4 is a schematic diagram of an electric energy distribution system according to another embodiment of the present disclosure. Figure 3B Schematic diagram of an electric energy distribution system according to another embodiment of the present disclosure. In this embodiment, the electric energy distribution system 300 is a series-parallel type electric energy distribution and supply system, which can be applied to DC-DC converters, DC-AC converters, AC-DC converters, and AC-AC converters, but the embodiments of the present disclosure are not limited thereto. Please refer to Figure 3A or Figure 3B The power distribution system 300 includes a first power module 310 and a second power module 320. The first power module 310 is provided with a first impedance component 311, such as Figure 3A As shown. Figure 3A In the embodiment of the present invention, the first power module 310 and the first impedance component 311 are the same or similar to the first power module 110 and the first impedance component 111 of FIG. 1 , and can be referred to as Figure 1A In addition, the first power module 310 is provided with a first impedance component 311 and a first switch component 312, such as Figure 3B As shown. Figure 3B In the embodiment of the present invention, the first power module 310, the first impedance component 311 and the first switch component 312 are connected to Figure 1B The first power module 110, the first impedance component 111 and the first switch component 112 are the same or similar, and can be referred to Figure 1A The embodiments of the present invention are described in detail, so they will not be repeated here.

[0076] The second power module 320 is provided with a second impedance component 321. In particular, the second power module 320 includes a third power module 330 and a fourth power module 340. In addition, the second impedance component 321 includes a third impedance component 331 and a fourth impedance component 341. The third impedance component 331 is provided in the third power module 330, and the fourth impedance component 341 is provided in the fourth power module 340. In some embodiments, Figure 3AAs shown, the first impedance component 311, the second impedance component 321, the third impedance component 331 and the fourth impedance component 341 are variable impedance components or digital variable impedance components, but the embodiment of the present disclosure is not limited thereto. In some embodiments, as Figure 3A As shown, the first impedance component 311, the second impedance component 321, the third impedance component 331 and the fourth impedance component 341 can be set in a virtual manner, for example, by executing a software, but the embodiment of the present disclosure is not limited thereto. In some embodiments, as Figure 3B As shown, the first impedance component 311, the second impedance component 321, the third impedance component 331 and the fourth impedance component 341 respectively include resistors, capacitors or inductors, but the embodiments of the present disclosure are not limited thereto. In some embodiments, as Figure 3B As shown, the first impedance component 311 , the second impedance component 321 , the third impedance component 331 and the fourth impedance component 341 are fixed impedance components or semi-fixed impedance components, respectively, but the embodiment of the disclosure is not limited thereto.

[0077] In this embodiment, the fourth power module 340 and the third power module 330 have different specifications. For example, in some embodiments, the third power module 330 and the fourth power module 340 may be of different brands and have different power levels. In some embodiments, the third power module 330 and the fourth power module 340 may be of the same brand and have different power levels. Alternatively, the third power module 330 and the fourth power module 340 may be batteries (e.g., decommissioned batteries), power supplies, or other suitable power supply devices, but the disclosed embodiments are not limited thereto.

[0078] In this embodiment, the third impedance component 331 refers to admittance, which is the reciprocal of impedance and is essentially still a resistor, capacitor, or inductor. The admittance value of the third impedance component 331 can match the electrical energy of the third power module 330. For example, when the power or electrical energy that the third power module 330 can provide is 4kW or 4kWh, the admittance value of the third impedance component 331 is, for example, 4. For example, when the power or electrical energy that the third power module 330 can provide is 2kW or 2kWh, the admittance value of the third impedance component 331 is, for example, 2. The manner in which the admittance values ​​of the remaining third impedance components 331 are matched to the electrical energy of the third power module 330 can be inferred similarly.

[0079] In addition, the fourth impedance component 341 of this embodiment, like the third impedance component 331, is referred to as an admittance. The admittance value of the fourth impedance component 341 can be matched to the power of the fourth power module 340. For example, when the power or power provided by the fourth power module 340 is 3 kW or 3 kWh, the admittance value of the fourth impedance component 341 is, for example, 3. For example, when the power or power provided by the fourth power module 340 is 1 kW or 1 kWh, the admittance value of the fourth impedance component 341 is, for example, 1. The same applies to the matching of the admittance value of the fourth impedance component 341 with the power of the fourth power module 340.

[0080] In this embodiment, the first power module 310 can provide first power based on the first power distribution information corresponding to the first impedance component 311, the second power module 320 can provide second power based on the second power distribution information corresponding to the second impedance component 321, the third power module 330 can provide third power based on the third power distribution information corresponding to the third impedance component 331, and the fourth power module 340 provides fourth power based on the second power distribution information corresponding to the fourth impedance component 341, wherein the second power, for example, includes the third power and the fourth power.

[0081] Specifically, the first power module 310 is connected in parallel with the second power module 320, the first impedance component 311 is connected in series with the second impedance component 321, the third power module 330 is connected in series with the fourth power module 340, and the third impedance component 331 is connected in parallel with the fourth impedance component 341. Furthermore, the end of the first impedance component 311 not connected to the second impedance component 321 can, for example, receive a voltage source control signal VS provided by an external device, and the end of the second impedance component 321 not connected to the first impedance component 311 can, for example, be connected to a ground terminal. Furthermore, the end of the third impedance component 331 connected to the fourth impedance component 341 can, for example, receive a current source control signal CS, and the other ends of the third impedance component 331 and the fourth impedance component 341 can, for example, be connected to a ground terminal. In this embodiment, the external device is, for example, a voltage source, but embodiments of the present disclosure are not limited thereto.

[0082] During operation of the power distribution system 300, an external device may provide a voltage source control signal VS to the first impedance element 311 of the first power module 310. The first impedance element 311 and the second impedance element 321 may then generate first power distribution information and second power distribution information, respectively, based on the voltage source control signal VS.

[0083] For example, assuming the first power module 310 can provide 6 kWh of power, the corresponding impedance value of the first impedance element 311 is 6, and the second power module 320 can provide 4 kWh of power, the corresponding impedance value of the second impedance element 321 is 4. Assuming the load power demand is 6 kWh, according to the current impedance value settings, the first power module 310 needs to provide 60% of the power (100% * 6 / (6 + 4)), that is, 6 kWh * 60% = 3.6 kWh, while the second power module 320 needs to provide 40% of the power (100% * 4 / (6 + 4)), that is, 6 kWh * 40% = 2.4 kWh. At this time, based on the load power demand of 6 kWh, the voltage source control signal VS is generated to be 6V. With the series connection of the first impedance element 311 and the second impedance element 321, the voltage source control signal VS is divided to generate the first power distribution information and the second power distribution information. The first power distribution information is, for example, (voltage source control signal VS*(impedance value of the first impedance component 311) / (impedance value of the first impedance component 311+impedance value of the second impedance component 321), that is, 6*(6 / (6+4))=3.6). The second power distribution information is, for example, (voltage source control signal VS*(impedance value of the second impedance component 321) / (impedance value of the first impedance component 311+impedance value of the second impedance component 321), that is, 6*(4 / (6+4))=2.4.

[0084] Next, the first power module 310 can generate 3.6 kWh of first power based on the first power distribution information (e.g., 3.6) corresponding to the first impedance component 311, and the second power module 320 can generate 2.4 kWh of second power based on the second power distribution information (e.g., 2.4) corresponding to the second impedance component 321. Therefore, the power distribution system 300 can provide 6 kWh of power, i.e., 3.6 kWh plus 2.4 kWh.

[0085] Furthermore, the third impedance element 331 and the fourth impedance element 341 can respectively generate third power distribution information and fourth power distribution information based on the current source control signal CS provided by the second impedance element 321. For example, assuming that the third power module 330 can provide 2.4 kWh of power, the corresponding admittance value of the third impedance element 331 is 2.4, and the fourth power module 340 can provide 1.6 kWh of power, the corresponding admittance value of the fourth impedance element 341 is 1.6.

[0086] At this point, when the power demand of the second power module 320 is 2.4 kWh, according to the current admittance value setting, the third power module 330 needs to provide 60% of the power (100% * 2.4 / (2.4 + 1.6)), that is, 2.4 kWh * 60% = 1.44 kWh, and the fourth power module 340 needs to provide 40% of the power (100% * 1.6 / (2.4 + 1.6)), that is, 2.4 kWh * 40% = 0.96 kWh. At this time, based on the load power demand of 2.4 kWh, the current source control signal CS is generated to be 2.4 A. Combined with the parallel connection of the third impedance element 331 and the fourth impedance element 341, the current source control signal CS is split to generate the third power distribution information and the fourth power distribution information. The third power distribution information is, for example, (current source control signal CS*(admittance value of the third impedance component 331) / (admittance value of the third impedance component 331+admittance value of the fourth impedance component 341), i.e., 2.4*(2.4 / (2.4+1.6))=1.44. The fourth power distribution information is, for example, (current source control signal CS*(admittance value of the fourth impedance component 341) / (admittance value of the third impedance component 331+admittance value of the fourth impedance component 341), i.e., 2.4*(1.6 / (2.4+1.6))=0.96.

[0087] Then, the third power module 330 can generate a third power corresponding to 1.44 kWh based on the third power distribution information (e.g., 1.44) corresponding to the third impedance component 331, and the fourth power module 340 can generate a fourth power corresponding to 0.96 kWh based on the fourth power distribution information (e.g., 0.96) corresponding to the fourth impedance component 341. Since the power distribution system 300 only needs to generate power according to load demand, the power supply specifications of the power distribution system 200 are not limited. The power distribution can have a mixed power supply with different specifications, and the corresponding power is provided by the power distribution information corresponding to the impedance component set in the power module, which can effectively reduce the complexity of the circuit design and increase the convenience of use.

[0088] like Figure 3A As shown, the third impedance component 331 and the fourth impedance component 341 are configured, for example, as variable impedance components or digital variable impedance components. When the third power module 330 and the fourth power module 340 are normal, the third impedance component 331 and the fourth impedance component 341 are controlled to not be open-circuited. Then, the third impedance component 331 and the fourth impedance component 341 can process the current source control signal CS using a shunt method according to the above embodiment to generate third power distribution information and fourth power distribution information. Subsequently, the third power module 330 can provide the third power according to the third power distribution information, and the fourth power module 340 can provide the fourth power according to the fourth power distribution information.

[0089] In addition, when the third power module 330 or the fourth power module 340 fails, the third impedance component 331 or the fourth impedance component 341 can be controlled to be open circuited, so that the third power module 330 or the fourth power module 340 can provide corresponding power again.

[0090] For example, when the fourth power module 340 fails, since the load demand remains at 2.4 kWh, the third power module 330 is required to provide 100% of the power (100% * 2.4 / (2.4 + 0)), i.e., 2.4 kWh * 100% = 2.4 kWh. The third impedance element 331 can re-obtain the third power distribution information based on the current source control signal CS, e.g., 2.4 * (2.4 / (2.4 + 0)) = 2.4. Then, the third power module 330 can generate a third power corresponding to 2.4 kWh based on the re-obtained third power distribution information (e.g., 2.4). In this way, even in the event of a failure, the impedance element configured for the failed power module is opened, so that the fourth power module 340 does not output energy. Similarly, in this embodiment, to maintain the operation of the power distribution system 300, the faulty power module is typically replaced with an internal diode or an external current path to maintain circuit connectivity. This also facilitates removal of the fourth power module 340 for maintenance. Therefore, the functioning power modules re-obtain the corresponding power distribution information based on their impedance components and provide corresponding power, thereby increasing ease of use.

[0091] In addition, if Figure 3B As shown, the power distribution system 300 further includes a third switch assembly 332 and a fourth switch assembly 342. The third switch assembly 332 is connected in series with the third impedance assembly 331, that is, the third switch assembly 332 is connected between the third impedance assembly 331 and the ground. The fourth switch assembly 342 is connected in series with the fourth impedance assembly 341, that is, the fourth switch assembly 342 is connected between the fourth impedance assembly 341 and the ground.

[0092] When the third power module 330 and the fourth power module 340 are normal, the third switch element 332 and the fourth switch element 342 are controlled to be conductive. Then, the third impedance element 331 and the fourth impedance element 341 can process the current source control signal CS by shunting according to the above embodiment to generate third power distribution information and fourth power distribution information. Subsequently, the third power module 330 can provide the third power according to the third power distribution information, and the fourth power module 340 can provide the fourth power according to the fourth power distribution information.

[0093] Furthermore, when a fault occurs in the third power module 330 or the fourth power module 340, the third switch component 332 or the fourth switch component 342 is controlled to be non-conductive, thereby opening the third impedance component 331 or the fourth impedance component 341. In this case, the third power module 330 or the fourth power module 340 can resume providing the corresponding power.

[0094] For example, when the fourth power module 340 fails, since the power demand of the second power module 320 is still 2.4 kWh, the third power module 330 is now required to provide 100% of the power (100% * 2.4 / (2.4 + 0)), that is, 2.4 kWh * 100% = 2.4 kWh. The third impedance element 331 can re-obtain the third power distribution information based on the current source control signal CS, for example, 2.4 * (2.4 / (2.4 + 0)) = 2.4. Then, the third power module 330 can generate a third power corresponding to 2.4 kWh based on the re-obtained third power distribution information (e.g., 2.4).

[0095] In this way, even if a fault occurs, the impedance component configured for the faulty power module is short-circuited (for example, the first impedance component 311 configured for the first power module 310 is short-circuited) or open-circuited (for example, the third impedance component 331 configured for the third power module 330 is open-circuited or the fourth impedance component 341 configured for the fourth power module 340 is open-circuited), the normal power module re-obtains the corresponding power distribution information based on its impedance component and provides the corresponding power, thereby increasing the convenience of use.

[0096] In some embodiments, as Figure 3B As shown, when the first impedance component 311, the third impedance component 331 and the fourth impedance component 341 are physical components, the first switch component 312, the third switch component 332 and the fourth switch component 342 can also be physical components, but the embodiments of the present disclosure are not limited thereto. In some embodiments, as Figure 3B As shown, when the first impedance component 311, the third impedance component 331 and the fourth impedance component 341 are set in a virtual manner, the first switch component 312, the third switch component 332 and the fourth switch component 342 can also be set in a virtual manner, but the embodiments of the present disclosure are not limited thereto.

[0097] In the above embodiment, the number of power modules included in the power distribution system 300 is two, namely the first power module 310 and the second power module 320, or the number of power modules included in the second power module 320 is two, namely the third power module 330 and the fourth power module 340, but the embodiments of the present disclosure are not limited thereto. The number of the above power modules can be three or more, and each power module is provided with a corresponding impedance component, and each power module can provide corresponding power according to the power distribution information corresponding to its impedance component. In addition, the operation of three or more power modules can refer to the description of the above embodiment, so it will not be repeated here.

[0098] Figure 4 FIG. 4 is a schematic diagram of an electric energy distribution system according to another embodiment of the present disclosure. Figure 5A for Figure 4 A waveform diagram showing the corresponding relationship between the power provided by the power modules corresponding to the first impedance component, the second impedance component, the third impedance component and the fourth impedance component and the power demand of the load. Figure 5B for Figure 4 A waveform diagram showing the corresponding relationship between the power provided by the power modules corresponding to the fifth impedance component, the sixth impedance component, and the seventh impedance component and the power requirement of the power module corresponding to the fourth impedance component. Figure 5C for Figure 4 Another waveform diagram of the corresponding relationship between the power provided by the power modules corresponding to the first impedance component, the second impedance component, the third impedance component and the fourth impedance component and the load power demand. In this embodiment, the power distribution system 400 is a series-parallel power distribution and supply system. Please refer to Figure 4 、 Figure 5A 、 Figure 5B and Figure 5C The power distribution system 400 includes a first impedance element 410 , a second impedance element 420 , a third impedance element 430 , and a fourth impedance element 440 . In addition, the fourth impedance element 440 includes a fifth impedance element 450 , a sixth impedance element 460 , and a seventh impedance element 470 .

[0099] In this embodiment, the first impedance component 410, the second impedance component 420, the third impedance component 430 and the fourth impedance component 440 are connected in series. In addition, the impedance value of the first impedance component 410 is, for example, 6, the impedance value of the second impedance component 420 is, for example, 3, the impedance value of the third impedance component 430 is, for example, 2, and the impedance value of the fourth impedance component 440 is, for example, 1. Figure 5AIn FIG, curve S11 corresponds to the power required to be provided by the power module corresponding to the first impedance component 410, curve S12 corresponds to the power required to be provided by the power module corresponding to the second impedance component 420, curve S13 corresponds to the power required to be provided by the power module corresponding to the third impedance component 430, and curve S14 corresponds to the power required to be provided by the power module corresponding to the fourth impedance component 440. Figure 5A It can be seen that, assuming that the load power demand is 6 kWh, according to the current impedance value setting, the power module corresponding to the first impedance component 410 needs to provide 6 kWh*(6 / (6+3+2+1))=3 kWh of power, the power module corresponding to the second impedance component 420 needs to provide 6 kWh*(3 / (6+3+2+1))=1.5 kWh of power, the power module corresponding to the third impedance component 430 needs to provide 6 kWh*(2 / (6+3+2+1))=1 kWh of power, and the power module corresponding to the fourth impedance component 440 needs to provide 6 kWh*(1 / (6+3+2+1))=0.5 kWh of power.

[0100] Furthermore, assuming that the load power demand is 12 kWh, according to the current impedance value settings, the power module corresponding to the first impedance component 410 needs to provide 12 kWh*(6 / (6+3+2+1))=6 kWh of power, the power module corresponding to the second impedance component 420 needs to provide 12 kWh*(3 / (6+3+2+1))=3 kWh of power, the power module corresponding to the third impedance component 430 needs to provide 12 kWh*(2 / (6+3+2+1))=2 kWh of power, and the power module corresponding to the fourth impedance component 440 needs to provide 12 kWh*(1 / (6+3+2+1))=1 kWh of power.

[0101] In this embodiment, the fifth impedance component 450, the sixth impedance component 460 and the seventh impedance component 470 are connected in parallel. In addition, the admittance value of the fifth impedance component 450 is, for example, 0.5, the admittance value of the sixth impedance component 460 is, for example, 0.3, and the admittance value of the seventh impedance component 470 is, for example, 0.2. Figure 5B In FIG, curve S21 corresponds to the power required to be provided by the power module corresponding to the fifth impedance component 450, curve S22 corresponds to the power required to be provided by the power module corresponding to the sixth impedance component 460, and curve S23 corresponds to the power required to be provided by the power module corresponding to the seventh impedance component 470. Figure 5BIt can be seen that, assuming that the power module corresponding to the fourth impedance component 440 requires 0.5 kWh of power, according to the current impedance value setting, the power module corresponding to the fifth impedance component 450 needs to provide 0.5 kWh*(0.5 / (0.5+0.3+0.2))=0.25 kWh of power, the power module corresponding to the sixth impedance component 460 needs to provide 0.5 kWh*(0.3 / (0.5+0.3+0.2))=0.15 kWh of power, and the power module corresponding to the seventh impedance component 470 needs to provide 0.5 kWh*(0.2 / (0.5+0.3+0.2))=0.1 kWh of power.

[0102] Furthermore, assuming that the power module corresponding to the fourth impedance component 440 requires 1 kWh of power, according to the current impedance value setting, the power module corresponding to the fifth impedance component 450 needs to provide 1 kWh*(0.5 / (0.5+0.3+0.2))=0.5 kWh of power, the power module corresponding to the sixth impedance component 460 needs to provide 1 kWh*(0.5 / (0.5+0.3+0.2))=0.3 kWh of power, and the power module corresponding to the seventh impedance component 470 needs to provide 1 kWh*(0.5 / (0.5+0.3+0.2))=0.2 kWh of power.

[0103] exist Figure 5C In FIG, T1 and T2 represent time, curve S31 corresponds to the electric energy required by the load, curve S32 corresponds to the electric energy required to be provided by the power module corresponding to the first impedance component 410, curve S33 corresponds to the electric energy required to be provided by the power module corresponding to the second impedance component 420, curve S34 corresponds to the electric energy required to be provided by the power module corresponding to the third impedance component 430, and curve S35 corresponds to the electric energy required to be provided by the power module corresponding to the fourth impedance component 440. Figure 5C It can be seen that at time T1, assuming that the load power demand is 6kWh, according to the current impedance value setting, the power module corresponding to the first impedance component 410 can provide 3kWh of power, the power module corresponding to the second impedance component 420 can provide 1.5kWh of power, the power module corresponding to the third impedance component 430 can provide 1kWh of power, and the power module corresponding to the fourth impedance component 440 can provide 0.5kWh.

[0104] At time T2, assuming the load power demand is 12 kWh (i.e., an increase from 6 kWh to 12 kWh), according to the current impedance value setting, the power supply of the power module corresponding to the first impedance component 410 can be increased from 3 kWh to 6 kWh, the power supply of the power module corresponding to the second impedance component 420 can be increased from 1.5 kWh to 3 kWh, the power supply of the power module corresponding to the third impedance component 430 can be increased from 1 kWh to 2 kWh, and the power supply of the power module corresponding to the fourth impedance component 440 can be increased from 0.5 kWh to 1 kWh. In this way, the power distribution system 400 can immediately provide corresponding power according to the current impedance value setting based on different load power demands, thereby avoiding overuse of the power modules and increasing convenience in use.

[0106] Please merge references Figure 4 、 Figure 6 and Figure 7During time T3 when the power distribution system 400 is operating normally, assuming that the load power demand is 6 kWh, according to the current impedance value setting, the power module corresponding to the first impedance component 410 can provide 3 kWh of power, the power module corresponding to the second impedance component 420 can provide 1.5 kWh of power, the power module corresponding to the third impedance component 430 can provide 1 kWh of power, the power module corresponding to the fourth impedance component 440 can provide 0.5 kWh of power, the power module corresponding to the fifth impedance component 450 can provide 0.25 kWh of power, the power module corresponding to the sixth impedance component 460 can provide 0.15 kWh of power, and the power module corresponding to the seventh impedance component 470 can provide 0.1 kWh of power.

[0107] During the time T4 when an abnormality occurs in the power distribution system 400 (for example, the power module corresponding to the second impedance component 420 fails and the power module corresponding to the seventh impedance component 470 fails), assuming that the load power demand is still 6 kWh, according to the current impedance value setting, the power module corresponding to the first impedance component 410 can provide 4 kWh, that is, (6*6 / (6+0+2+1)) kWh of power, and the power module corresponding to the third impedance component 430 can provide approximately 1.33 kWh, that is, (6*2 / (6+0+2+1))kWh of electrical energy, the power module corresponding to the fourth impedance component 440 can provide approximately 0.67kWh, that is, (6*1 / (6+0+2+1))kWh of electrical energy, the power module corresponding to the fifth impedance component 450 can provide approximately 0.419kWh, that is, (0.67*0.25 / (0.25+0.15))kWh, and the power module corresponding to the sixth impedance component 460 can provide approximately 0.251kWh, that is, (0.67*0.15(0.25+0.15)). In this way, even if a fault occurs in the power distribution system 400, the faulty second impedance component 420 is controlled to be short-circuited and the seventh impedance component 470 is controlled to be open-circuited. The normal power modules can regain the corresponding power distribution information based on the impedance values ​​or admittance values ​​of their impedance components (i.e., the first impedance component 410, the third impedance component 430, the fourth impedance component 440, the fifth impedance component 450 and the sixth impedance component 460) and provide the corresponding 6 kWh of power. Therefore, the power distribution system has a backup function and can maintain output stability and convenience in use.

In some embodiments, the first power module and the second power module can be connected in series, and the first impedance component and the second impedance component can be connected in parallel.
