Description

TECHNICAL FIELD

[0001] The utility model relates to portable power supply technical field more specifically, it is a kind of power supply circuit power output distribution device. BACKGROUND

[0002] With the explosive growth of smart phones, notebook computers, new energy electric vehicles, photovoltaic industry and energy storage equipment, electronic power modules are more and more, and portable power supply products are more and more. Products are more and more miniaturized. Lithium batteries are widely used in mobile devices, and each product design will develop a specific charging scheme according to the selected battery characteristics, to complete the charging of the device most quickly and safely. Since lithium batteries are flammable and explosive, for safety, each has its own encrypted private protocol (generally not publicly disclosed, except for authorization), and mutual compatibility is not good. To make mobile devices more convenient and fast, the charging speed is getting faster and faster, and the power is getting bigger and bigger, how to re-distribute and expand the application of various adapters. Compatibility, practicality and convenient monitoring application have become a new topic. It is a problem to be solved to increase the expansion of other output ports without changing the original performance of the adapter.

[0003] In practice, high-power output devices have single application scenarios. For example, a certain 240W mobile phone charger, when used, only 213W peak power is actually used for charging for a short time of only a few seconds, and most of the time only 20-40W power is charged, which is very wasteful. After charging the mobile phone, most of the energy can be distributed to other devices for charging, but it cannot be done due to a single output port.

[0004] For another example, a certain 150W mobile phone charger has a maximum output voltage of only 11V, and many devices, including notebook computers, cannot be used. In addition, the USB charging protocol is constantly changing with the update of products, and the PD3.0 adapter can only support a maximum output voltage of 20V, and cannot support the function of PD3.1 devices.

[0005] When mobile phone manufacturers launch new products (increase battery capacity and shorten charging time), they will develop the best charging scheme (fast and safe) according to the selected battery characteristics. Other brand charging devices are not considered, and only one single port is often provided. If multiple devices need to be charged at the same time, multiple charging heads or more expensive multi-port charging heads must be purchased (such devices can meet the charging requirements of mobile phones, but may not be the best charging scheme, such as slow charging time and poor charging safety compared to the original), and the compatibility and expansion performance are not strong.

[0006] Similarly, electric vehicles also use lithium batteries for fast and safe charging. At the beginning, it is also fast charging, and when the battery temperature reaches the safety warning point (the time is very short), the charging power will be quickly reduced. Using this method can greatly improve the power utilization rate of the charging pile. The capacity of the charging pile can be increased several times.

[0007] The power industry is like a charging head. Every time it is updated, all the structures and circuits of the product are completely redesigned. It is a mandatory product certification. Each must obtain product certification.

[0008] Due to the single function and low practicality of the product, the charging equipment is updated quickly and the function requirement is higher and higher. In order to meet the equipment demand, only the expensive multi-port and new requirements such as PD3.1 product are reselected and purchased. The circuit needs to meet the EMI circuit, AC-DC control circuit, high-voltage gallium nitride switch tube, isolation transformer, DC-DC and port protocol circuit, and various certification certificates, resulting in high cost.

[0084] As Figure 1As shown, the power circuit power output distribution device (hereinafter referred to as the device) 1 provided by the utility model, including control unit (including AI control unit) 100, input end and output end, the input end has at least one, and is connected with control unit 100 respectively, and each input end is used for connecting power supply device or power adapter, and the input end is used for obtaining the power information (including voltage, current, power, maximum temperature and the like) of power supply device or power adapter, the output end has at least one, and is connected with control unit, and each output end is used for connecting electric device, and the output end is used for obtaining the power information (including voltage, current, power, maximum temperature and the like) of electric device.

[0085] The power circuit and data line with at least one pair of input end and output end are directly connected or connected through control switch in the utility model, or the power circuit with at least one pair of input end and output end is directly connected or connected through control switch;

[0086] The control unit 100 obtains the input power through the input end, and according to the output power of each output end, the control unit 100 is output to each output end after redistribution.

[0087] In the case that the dedicated power supply device or power adapter can only charge a single device, the output voltage range is small (small voltage and large current), the application scene is less, and the power supply device with large power has extremely short high-power charging time, through the combined application of the device and the power supply device or power adapter, without changing the performance and compatibility of the original power supply device or power adapter, the output power is redistributed and intelligently controlled by adjusting the voltage range and expanding the output port, and the original product practicality and application range are expanded.

[0088] For example, the 240W charger, in actual use, the 213W peak charging time is only a few seconds, and the charging power is only 20-40W (power utilization rate is not large 2) most of the time. The maximum output voltage of 150W charger is only 11V (150W notebook cannot be used). The two chargers are too wasteful. The two chargers are combined with the device, without changing the previous fast charging performance and safety, and can meet the current most mobile terminal device applications, and can charge multiple devices at the same time. The device is combined to complete conversion by DC-DC converter, and the cost is extremely low, the update is easy, the authentication is very easy, and the device can be controlled by Ai (OTA update through wireless module).

[0089] As Figure 1 , in the first embodiment, the input end has one, which is input end one 131, and the output end has three, which are output end one 161, output end two 162 and output end three 163.

[0090] The device has three power output circuits, the first power output circuit is directly connected between the input end one 131 and the output end one 161; the second power output circuit is connected between the input end one 131 and the output end two 162 through the first DC converter 111; and the third power output circuit is connected between the input end one 131 and the output end three 163 through the second DC converter 112.

[0091] At the same time, the communication data line of the input end one 131 is directly connected with the communication data line of the output end one 161. In this way, the power signal and the data signal of the input end one 131 are directly connected with the output end one 161, which is equivalent to that the first port 261 of the power adapter 2 is directly connected with the power equipment one port 331. Obviously, after the power adapter 2 is connected with the device 1, the power adapter 2 still has all the performance characteristics, load capacity (the same compatibility and safety) of the original power adapter, and realizes the expansion of new functions without changing the original performance of the power adapter.

[0092] The control unit 100 is connected with the input end one 131, the output end one 161, the output end two 162, the output end three 163, the current sensor Rcs1, the current sensor Rcs3, the current sensor Rcs4, the current sensor Rcs5, the first DC converter 111 and the second DC converter 112 respectively.

[0093] In this embodiment, two cases of connecting the power equipment through the output end one 161 and not connecting the power equipment are specifically explained.

[0094] The case of connecting the power equipment through the output end one 161:

[0095] The control unit 100 knows the power information (including the maximum voltage, the maximum current and the rated power) that the power adapter 2 can provide to the input end one 131 through the input end one 131. The connected power equipment information (including the required output voltage and current) is obtained through the output end one 161, the output end two 162 and the output end three 163. The output of the output end one 161 is completely determined by the protocol between the power adapter 2 and the power equipment one port 331, and is not controlled by the control unit 100, that is, the charging equipment connected with the output end one 161 is preferentially satisfied. The control unit 100 analyzes and calculates the maximum power P131imax@V331 that the input end one 131 can provide at the current voltage, subtracts the output power Pom=V331*I331 of the output end one 161, and obtains the remaining power Pirem after the output end one 161, which is distributed to the power equipment connected with the output end two 162 and the output end three 163 through the control of the first DC converter 111 and the second DC converter 112. The efficiency is as follows:

[0096] η=(Pom+Po1+Po2) / Pi=(V331*I331+V332*I332+V333*I333) / (V131*I131).

[0097] In fact, the efficiency of the control unit should be calculated as follows: ignoring the loss V161=V331, V162=V332, V163=V333. In all examples, V331, V332, V333, I331, I332, and I333 represent V161, V162, V163, I161, I162, and I163 respectively, and they will not be repeated here.

[0098] η=(Pom+Po1+Po2) / Pi=(V161*I161+V162*I162+V163*I163) / (V131*I131).

[0099] The following are the output specifications of a mobile phone adapter:

[0100] If there is only one Type-C port, the voltage and current output specifications are: 3.3-5V / 8A Max, 5.2-11V / 9.1A Max, 12-18V / 10A Max, and 20V / 12A Max;

[0101] When the voltage V331 = 20V, the maximum output power P131imax@20V = 20*12 = 240W;

[0102] When the voltage V331 = 15V, the maximum output power P131imax@15V = 15*10 = 150W;

[0103] When the voltage V331 = 11V, the maximum output power P131imax@11V = 11*9.1 = 100W;

[0104] When the voltage V331 = 5V, the maximum output power P131imax@5V = 5*8 = 40W.

[0105] It can be seen that the maximum output power of the power adapter 2 changes with the change of the voltage V331 (V331=V131) (ignoring the loss and retaining some margin in actual application).

[0106] When the output terminal 161 is charging the mobile phone, the initial voltage is V331 (V331=20V) and the current is 12A, but the time is very short and the power is around 20-40W most of the time.

[0107] When the power adapter 2 charges the port 331 of the power device with 40W, the voltage V331 = 20V, at this time the power provided to the output two 162 and the output three 163 is 240W-40W = 200W (ignoring the loss should be left some margin), there are eight energy to charge other power devices (this embodiment is given three output, can also be four, five, six output, etc.).

[0108] The maximum output voltage of the power adapter 2 is 20V, which can meet the power device of PD3.0, but cannot meet the power device of PD3.1 (such as V = 28V, 36V, 48V).

[0109] The first DC converter 111 and the second DC converter 112 are selected as Boost or Buck-Boost topology circuit, which can make the voltage of the output two 162 and the output three 163 become 28V, 36V, 48V.

[0110] The power adapter 2 cooperates with the device 1 to realize the compatibility of the PD3.1 product, which expands the practicality and application range of the product.

[0111] The output one 161 is not connected to the power device:

[0112] The control unit 100 obtains the power information (including the maximum voltage, the maximum current and the rated power) provided by the power adapter 2 to the input one 131 through the input one 131. The connected power device information (including the required output voltage and current) is obtained through the output two 162 and the output three 163.

[0113] The control unit 100 adjusts the output voltage of the power adapter 2 as the input voltage of the first DC converter 111 and the second DC converter 112.

[0114] The efficiency η = (Po1+Po2) / Pi = (V332*I332+V333*I333) / (V131*I131) is obtained, and the power adapter can provide different energy (load capacity) at different output voltages. The control unit 100 selects according to the priority level to meet the following requirements:

[0115] (1) meet the output two 162 and the output three 163 all energy requirements, high efficiency;

[0116] (2) does not meet the output two 162 and the output three 163 all energy, provides enough energy;

[0117] (3) does not meet the output two 162 and the output three 163 all energy, provides the same energy, high efficiency.

[0118] The control unit 100 first takes the maximum voltage Vimax that the power adapter 2 can output as the input voltage of the first DC converter 111 or the second DC converter 112 (or not), at which time the maximum power of the first port 261 of the power adapter 2 is P261@20V (as the parameters of the previous 240W power adapter, the power at the maximum voltage of 20V is P261@20V=240W), and the control unit 100 adjusts the output of the first DC converter 111 and the second DC converter 112 to supply power to the power-consuming devices connected to the output two 162 and the output three 163. The efficiency η=(Po1+Po2) / Pi=(V332*I332+V333*I333) / (V131*I131) is obtained.

[0119] The voltage V261 is gradually reduced, and the efficiency η at this time is calculated. A quick judgment can provide all the energy or enough energy to the output two 162 and the output three 163 at all voltages, and the voltage at the highest efficiency η is taken as the input voltage of the first DC converter 111 or the second DC converter 112.

[0120] The control unit 100 analyzes and calculates the maximum power P131imax@V331 that the input one 131 can provide at the current voltage, and the control unit 100 distributes the power-consuming devices connected to the output two 162 and the output three 163 by controlling the first DC converter 111 and the second DC converter 112.

[0121] In the above manner, all the performance of the original power adapter is retained, the efficiency η is monitored in real time, the input condition (voltage, current, power) at the highest efficiency η is intelligently selected, the power-consuming devices connected to the output two 162 and the output three 163 are distributed by the control unit 100 controlling the first DC converter 111 and the second DC converter 112, and the control is relatively complex.

[0122] There is another cost-effective and simple control method: the first DC converter 111 and the second DC converter 112 are Buck.

[0123] When the output one 161 is just connected to a power-consuming device, the high-power charging is as follows: the voltage V331=20V (charging starts or connecting a notebook), and if the voltage difference ΔV of the first DC converter 111 and the second DC converter 112 is approximately 1.5V, the output voltage range of the output two 162 and the output three 163 is 0-18.5V, and the application scenario is relatively wide. When the mobile phone is almost fully charged, the voltage drops to V331=5V, and the output voltage of the output two 162 and the output three 163 is 0-3.5V, and the application scenario is less (but Example Three can solve this problem).

[0124] When the output terminal 161 is not connected to an electrical device, the voltage Vomax = V332. When the voltage V333 is a high voltage, it changes dynamically.

[0125] The control unit 100 obtains power information (including the required output voltage and current) from the connected electrical device via output terminal 2 162 and output terminal 3 163. The control unit 100 requires that the voltage V261 at the first port 261 of the power adapter 2 be greater than or equal to Vomax + ΔV. The control unit 100 adjusts the output voltage of the power adapter 2 as the input voltage to the first DC converter 111 or the second DC converter 112. The efficiency η is calculated as follows: (Po1 + Po2) / Pi = (V332 * I332 + V333 * I333) / (V131 * I131).

[0126] The power adapter 2 can provide different energy (load capacity) when outputting different voltages. The control unit 100 selects the following requirements according to the priority level:

[0127] (1) Satisfy all energy requirements of output terminal 2 162 and output terminal 3 163 and have high efficiency;

[0128] (2) not meeting the full energy of output terminal two 162 and output terminal three 163 and providing sufficient energy;

[0129] (3) It does not satisfy that the output terminal 2 162 and the output terminal 3 163 all have the same energy and provide the same energy with high efficiency.

[0130] The above method retains all the performance of the original power adapter and monitors the efficiency η in real time, intelligently selects the input conditions (voltage, current, power) when the efficiency η is the highest, and controls the first DC converter 111 and the second DC converter 112 through the control unit 100 to distribute them to the electrical equipment connected to the output terminal 2 162 and the output terminal 3 163. The control is relatively complex.

[0131] Alternatively, the voltage V261 can be directly set to V261max. Typically, this maximum voltage allows power adapter 2 to output a greater amount of power, such as the previously mentioned 240W power adapter, where power P261 = 240W @ 20V. The control unit 100 controls the first DC converter 111 and the second DC converter 112 to distribute the corresponding voltage and current to the power-consuming devices connected to output terminals 2 162 and 3 163. If a power adapter with an output voltage higher than the PD3.0 or PD3.1 voltage by more than ΔV is connected, the device can adjust the input voltage through the protocol to meet the power requirements for both PD3.0 and PD3.1 devices.

[0132] For example: the control unit 100 adjusts the voltage V261 = 21-22V through the protocol, which satisfies the voltage V332 = 20V or V333 = 20V after Buck, which satisfies PD3.0;

[0133] The control unit 100 adjusts the voltage V261 = 29-30V through the protocol, which satisfies the voltage V332 = 28V or V333 = 28V after Buck, which satisfies PD3.1;

[0134] The control unit 100 adjusts the voltage V261 = 37-38V through the protocol, which satisfies the voltage V332 = 36V or V333 = 36V after Buck, which satisfies PD3.1;

[0135] The control unit 100 adjusts the voltage V261 = 49-50V through the protocol, which satisfies the voltage V332 = 48V or V333 = 48V after Buck, which satisfies PD3.1.

[0136] This way the first DC converter 111 and the second DC converter 112 are Buck, which is low in cost, high in performance-price ratio and easy to control, but the PD3.0 power adapter cannot realize the requirement of upgrading PD3.1 with the device (the second embodiment can solve this problem).

[0137] In the first embodiment, the output end two 162 is connected to the power device two port 332, and the output end three 163 is connected to the power device three port 333.

[0138] As shown in Figure 2 The second embodiment is different from the first embodiment in that a third DC converter 113 is added between the input end one 131 and the first DC converter 111 and the second DC converter 112, and different scene applications can be realized by transforming the DC converter topology combination between them, which can solve the shortcoming that the PD3.0 power adapter cannot meet the charging requirements of the PD3.1 power device with the device 1 in the first embodiment.

[0139] When the first DC converter 111 and the second DC converter 112 are Buck, the third DC converter 113 is added as a boost (Boost) or a buck-boost (Buck-Boost) to be easily realized.

[0140] As shown in Figure 3 The third embodiment is different from the first embodiment in that two switch units, a first switch unit 121 (power switch) and a second switch unit 122 (a group of data switches), are added between the input end one 131 and the output end one 161. The first switch unit 121 is a power signal on-off switch, and the second switch unit 122 is a data signal on-off switch.

[0141] The first DC converter 111 and the second DC converter 112 use Buck circuits (this circuit has low cost and simple control, but is not limited to this), and the output terminal 161 is connected to a load.

[0142] When the mobile phone is almost fully charged, the voltage of the first port 331 of the power-consuming device will drop to V331 = 5V. When the mobile phone is almost fully charged, if the voltage difference ΔV between the first DC converter 111 and the second DC converter 112 is 1.5V, the output voltage of the second output terminal 162 and the third output terminal 163 is 0-3.5V, which has few application scenarios (refer to the first embodiment).

[0143] When the control unit 100 detects that the first port 331 of the power-consuming device is fully charged, it disconnects the first switch unit 121 and the second switch unit 122 and resets the voltage V261 of the first port 261 of the power adapter 2 to V261max, or the voltage at which the power adapter 2 outputs its maximum power. If the power adapter 2 originally shipped with the power-consuming device is not connected to the output port 161, or if the power adapter 2 originally shipped with the power-consuming device needs to be charged preferentially to the power-consuming devices connected to the output ports 2 162 and 3 163 (this can be set via the app for devices with wireless modules), V261 can be set to V261max.

[0144] like Figure 4 As shown, the fourth embodiment differs from the third embodiment in that a third DC converter 113 is added between the input terminal 131 and the first DC converter 111 and the second DC converter 112. The purpose is the same as that of the first embodiment.

[0145] like Figure 5 As shown, the difference between the fifth embodiment and the first embodiment is that a second input terminal 132 and a fourth output terminal 166 are added, and both the second input terminal 132 and the fourth output terminal 166 are DC power interfaces.

[0146] Input terminal two 132 is output through three power output circuits. The first power output circuit is a direct connection between input terminal two 132 and output terminal four 166; the second power output circuit is a connection between input terminal two 132 and the first DC converter 111 and then connected to output terminal two 162; the third power output circuit is a connection between input terminal two 132 and the second DC converter 112 and then connected to output terminal three 163.

[0147] The traditional power adapter is a DC interface, the input terminal 2 132 is connected to the third port 263 of the power adapter 2, and the output terminal 4 166 is connected to the fourth port 336 of the power device (the original charging device interface), so that the traditional power adapter can charge the original charging device while the excess energy is supplied to the second port 332 and the third port 333 of the power device.

[0148] The current of the interface with data signal and power signal (such as USB A, USB C interface) is too small, generally the highest is 5-6A. By using the existing interface with data signal and power signal integration and taking the data information as the protocol communication channel, the DC interface can pass through a large current.

[0149] The power interface of the input end one 131 and the input end two 132 is connected at the same time only one (may not be, the schematic diagram is not illustrated), or the input end one 131 is used as a data information interface, and the input end two 132 is used as a high-power power interface.

[0150] As shown in Figure 6 , the sixth embodiment is different from the fifth embodiment in that a third DC converter 113 is added between the input end one 131 and the input end two 132 and the first DC converter 111 and the second DC converter 112, and different scene applications can be realized by converting the power supply conversion topology combination between them.

[0151] Figure 7 , Figure 8 and Figure 9 A wireless module is added to facilitate intelligent control, and the device is connected with the terminal to complete control through an APP.

[0152] As shown in Figure 7 , the seventh embodiment is different from the sixth embodiment in that the device is provided with a wireless module to facilitate intelligent control. The wireless module includes but is not limited to Zeebe, Wifi, Bluetooth, Lora, 4G, 5G, 6G and Xingshan of Huawei, etc.

[0153] In the embodiment, an internal wireless circuit unit 102 is arranged, and the internal wireless circuit unit 102 is connected with the control unit 100. The internal wireless circuit unit 102 is arranged in the device (refer to Figure 18 , and the external wireless circuit unit 104 can also be connected with the USB interface), so that the device can be wirelessly connected with a mobile phone, a tablet computer and a computer, and the charging state can be clearly displayed on the mobile phone, the tablet computer and the computer by installing a corresponding program (such as an App) on the mobile phone, the tablet computer and the computer, and the priority level of the charging and the remote intelligent control system can be adjusted and controlled through the Internet. Remote monitoring of the charging state, control of the switch, power distribution, timing of turning off the power, timing of charging and other functions can be realized.

[0154] As shown in Figure 8 , the eighth embodiment is different from the fifth embodiment in that the first switch unit 121 (a power switch), the second switch unit 122 (a group of data switches), the third switch unit 123 (a power switch) and the internal wireless circuit unit 102 are added.

[0155] The power interface of the input end one 131 and the input end two 132 can only be connected simultaneously.

[0156] The embodiment has three output applications and control modes:

[0157] The first mode: the input end one 131 is output through a three-way power output circuit, the first power output circuit is connected with the output end one 161 after the input end one 131 is connected with the first switch unit 121, the second power output circuit is connected with the output end two 162 after the input end one 131 is connected with the first direct current converter 111, and the third power output circuit is connected with the output end three 163 after the input end one 131 is connected with the second direct current converter 112.

[0158] The communication data line of the input end one 131 is connected with the communication data line of the output end one 161 through the second switch unit 122.

[0159] The above is the control method of the general power of the USB, and the current, voltage and power are small.

[0160] The second mode: the input end two 132 is output through a three-way power output circuit, the first power output circuit is connected with the output end four 166 after the input end two 132 is connected with the third switch unit 123, the second power output circuit is connected with the output end two 162 after the input end two 132 is connected with the first direct current converter 111, and the third power output circuit is connected with the output end three 163 after the input end two 132 is connected with the second direct current converter 112.

[0161] At this time, the first power output can output high power, and the power parameters cannot be controlled due to the absence of the control signal.

[0162] The third mode: the input end two 132 is output through a three-way power output circuit, the first power output circuit is connected with the output end four 166 after the input end two 132 is connected with the third switch unit 123, the second power output circuit is connected with the output end two 162 after the input end two 132 is connected with the first direct current converter 111, and the third power output circuit is connected with the output end three 163 after the input end two 132 is connected with the second direct current converter 112. The communication data line of the input end one 131 is connected with the communication data line of the output end one 161 through the second switch unit 122.

[0163] At this time, the transmission of the large current, the large voltage and the large power has a group of input ends, that is, the input end one 131 is the first data signal input end, and the input end two 132 is the first large power input end. Also has a group of output ends, that is, the output end one 161 is the first data signal output end, and the output end four 166 is the first large power output end.

[0164] The first power output circuit is connected with a group of input interfaces, i.e. the first input end 131 and the output end one 161. The first input end 131 (at this time only a data interface) and the output end one 161 (at this time only a data interface) obtain power information (voltage, current, power) through the second input end 132 (a high-power interface) and the output end four 166 (a high-power interface) channel. The control unit 100 controls the second switch unit 122 (a data switch) and the third switch unit 123 (a power switch) to realize high-power output.

[0165] Figure 8 The power adapter 2 also contains a group of data ports (i.e. the first port 261) and a high-power power interface (i.e. the third port 263).

[0166] The power equipment 3 also contains a group of data ports (i.e. the power equipment one port 331) and a high-power power interface (i.e. the power equipment four port 336).

[0167] The internal wireless circuit unit 102 is connected with the control unit 100.

[0168] As Figure 9 The ninth embodiment is different from the eighth embodiment in that the third DC converter 113 is added between the input end one 131 and the input end two 132 and the first DC converter 111 and the second DC converter 112.

[0169] As above, the power interface of the input end one 131 and the input end two 132 is connected with only one at the same time (which can not be the case, and the schematic diagram is not illustrated), or the input end one 131 is used as a data information interface, and the input end two 132 is used as a high-power power interface.

[0170] As Figure 10 The tenth embodiment is different from the third embodiment in that the fifth DC converter 115 is added, and the fifth DC converter 115 is connected in parallel with the first switch unit 121. That is, the first power output circuit is connected with the output end one 161 through the parallel circuit of the first switch unit 121 and the fifth DC converter 115.

[0171] When the output end one 161 is not connected with the original power adapter 2, or although it is connected with the original power adapter 2, but the output end two 162 and the output end three 163 need to be charged preferentially:

[0172] If the first switch unit 121 and the second switch unit 122 are both turned on, the circuit structure becomes as Figure 1

[0173] If the first switch unit 121 and the second switch unit 122 are both turned off, the circuit structure becomes as Figure 11 ​The circuit structure of the eleventh embodiment (i.e. the twelfth embodiment);

[0174] If the first DC converter (111), the second DC converter (112) and the fifth DC converter (115) are Buck, it becomes as follows Figure 12 The circuit structure of the eleventh embodiment (i.e. the twelfth embodiment);

[0175] The voltage Vomax is equal to the highest voltage among V331, V332 and V333, which is dynamically changed.

[0176] The control unit 100 knows the power information (including the required output voltage and current) of the connected electrical equipment through the output terminal one 161, the output terminal two 162 and the output terminal three 163, and the control unit 100 requires the voltage V261 of the first port 261 of the power adapter 2 to be >= Vomax+ΔV. The control unit 100 adjusts the output voltage of the power adapter 2 as the input voltage of the first DC converter 111 and the second DC converter 112, and the efficiency η can be obtained as follows:

[0177] η = (Pom+Po1+Po2) / Pi = (V331*I331 V332*I332+V333*I333) / (V131*I131).

[0178] The power adapter 2 can provide different energy (load capacity) at different output voltages. The power adapter 2 selects according to the priority level to meet the following requirements:

[0179] (1) meet the energy requirements of the output terminal one 161, the output terminal two 162 and the output terminal three 163, and have high efficiency;

[0180] (2) do not meet the energy requirements of the output terminal one 161, the output terminal two 162 and the output terminal three 163, but provide enough energy;

[0181] (3) do not meet the energy requirements of the output terminal one 161, the output terminal two 162 and the output terminal three 163, but provide the same energy and have high efficiency.

[0182] The tenth embodiment has one more fifth DC converter 115 than the third embodiment. By disconnecting the first switch unit 121, the three output terminals can be charged simultaneously, and the input voltages V131 (V111=V112=V115

[0183] = V131) ≠ V331 (unlike the third embodiment, the voltage V131 = V331 when the output end 161 is connected to the electrical equipment, which is bound by the port 331 of the electrical equipment). It can also monitor the efficiency η in real time, intelligently select the input requirements, control the first DC converter 111, the second DC converter 112, and the fifth DC converter 115 to distribute voltage and current to the electrical equipment connected to the output end 161, the output end 162, and the output end 163, and there are three independent output ports, one more than the third embodiment.

[0184] The control unit 100 directly sets the voltage V261 = V261max (usually at this time the voltage is the highest power that the power adapter can output larger power), as mentioned earlier, the 240W power adapter, power P261 = 240W@20V. The control unit 100 controls the fifth DC converter 115, the first DC converter 111, and the second DC converter 112 to distribute voltage and current to the electrical equipment connected to the output end 161, the output end 162, and the output end 163.

[0185] This method is low in cost, high in performance, and simple in control. The power adapter of PD3.0 cannot meet the requirements of upgrading PD3.1 with this device (this problem can be solved by adding a third DC converter 113, as in the second embodiment). Buck is a step-down, so the output voltage becomes smaller. However, the device can adjust the input voltage through the protocol to meet the power supply requirements of PD3.1 devices if the connected output voltage is higher than the PD3.0 or PD3.1 voltage ΔV. The device can adjust the input voltage through the protocol to meet the power supply requirements of PD3.0 and PD3.1 devices if the connected output voltage is higher than the PD3.0 or PD3.1 voltage ΔV.

[0186] For example: the control unit 100 adjusts the voltage V261 = 21-22V through the protocol to meet the voltage V332 = 20V or V333 = 20V after Buck, which meets PD3.0;

[0187] The control unit 100 adjusts the voltage V261 = 29-30V through the protocol to meet the voltage V332 = 28V or V333 = 28V after Buck, which meets PD3.1;

[0188] The control unit 100 adjusts the voltage V261 = 37-38V through the protocol to meet the voltage V332 = 36V or V333 = 36V after Buck, which meets PD3.1;

[0189] The control unit 100 adjusts V261 = 49-50V through the protocol to meet the voltage V332 = 48V or V333 = 48V after Buck, which meets PD3.1.

[0190] The first and second switch units 121, 122 can be mechanically linked switches (or electronic switches). When the power supply connected to output terminal 161 is using the original power adapter 2, the first and second switch units 121, 122 are closed, giving priority to the optimal charging solution for output terminal 161. All three output terminals are charged simultaneously. When the power supply connected to output terminal 161 is not using the original power adapter 2, the first and second switch units 121, 122 are closed, allowing the three output terminals to operate independently. Output terminal 161 is compatible with the original power adapter and provides an additional independently functioning output port (see the first through ninth embodiments).

[0191] like Figure 16 The sixteenth embodiment differs from the tenth embodiment in that a fifth switch unit 125 is added, connected in parallel with the first DC converter 111. A seventh switch unit 127 is added, connected in parallel with the second DC converter 112. Specifically, the second power output circuit is connected from input terminal 131 through the parallel circuit of the fifth switch unit 125 and the first DC converter 111 to output terminal 2 162. The third power output circuit is connected from input terminal 131 through the parallel circuit of the seventh switch unit 127 and the second DC converter 112 to output terminal 3 163.

[0192] At the same time, a fourth switch unit 124 and a sixth switch unit 126 are added, so that the communication data line of input terminal 1 131 is directly connected to the communication data line of output terminal 1 161 through the second switch unit 122. The communication data line of input terminal 1 131 is directly connected to the communication data line of output terminal 2 162 through the fourth switch unit 124. The communication data line of input terminal 1 131 is directly connected to the communication data line of output terminal 3 163 through the sixth switch unit 126.

[0193] The advantage of this is that the output ports can be directly connected to the input ports, and all the performance of the original adapter can be obtained. And all ports can simultaneously meet the extremely fast and safe output.

[0194] As the previous 240W adapter, three mobile phones are connected at the same time. The control unit will give the first mobile phone interface direct connection input (data and power at the same time), at this time the adapter charges it at 213W high-power super-speed, while the second and third mobile phones can be divided into the remaining 27W power (for a very short time). When the first mobile phone completes the 213W high-power super-speed charging, the direct mode of the first mobile phone is disconnected, and the second mobile phone is replaced with the direct mode. At this time, the second mobile phone is charged at 213W high-power super-speed, while the remaining 27W power is divided to the first and third mobile phones. Soon the second mobile phone will also complete the 213W high-power super-speed charging, and the direct mode is cut off to replace the third mobile phone. Soon the third mobile phone will also complete the 213W high-power super-speed charging, and finally, the charging power of the three mobile phones will be charged at 40W->20W (there are still 120W-180W of power left, which can also meet the needs of three mobile phones). Three ports can achieve simultaneous super-speed and safe charging service. It can be seen that the 240W adapter can simultaneously meet the optimal charging mode of six mobile phones.

[0195] Obviously, in the sixteenth embodiment, all the output ports of the device can be directly connected to the output ports of the original adapter (power and data interface) through control, which is much higher than the utilization rate of the original adapter in the tenth embodiment. Of course, the device can also be partially connected to the output ports of the original adapter (not exemplified).

[0196] As Figure 13 , the thirteenth embodiment is different from the first embodiment in that the output end has two, output end one 161 and output end two 162, and a wireless charging transmitter 181 is added.

[0197] The device has three power output circuits, the first power output circuit is directly connected between the input end one 131 and the output end one 161, the second power output circuit is connected between the input end one 131 and the output end two 162 through the first DC converter 111, and the third power output circuit is connected between the input end one 131 and the wireless charging transmitter 181 through the second DC converter 112. The communication data line of the input end one 131 is directly connected to the communication data line of the output end one 161.

[0198] As Figure 14 , the fourteenth embodiment is different from the first embodiment in that an energy storage device 151 is added.

[0199] The power output distribution device of the power supply circuit has four power output circuits. The first power output circuit is directly connected between the input end one 131 and the output end one 161.
