Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The present application is described in detail below with reference to the accompanying drawings and implementation methods.

[0024] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of the first embodiment of the energy storage regulating circuit of the present application. In this embodiment, the energy storage regulating circuit 10 includes: a first energy storage circuit 11, a second energy storage circuit 12 and an electric energy conversion circuit 13.

[0025] Among them, a storage energy regulation circuit 10 provided in the present application is specifically used in any reasonable power supply architecture involving unstable power sources or unstable loads, such as photovoltaic and wind energy access, unstable loads such as motors and large engineering machinery, and large dynamic load equipment, so as to dynamically adjust the power supply output voltage to achieve uninterrupted and high-stability power supply requirements. This embodiment does not limit this.

[0026] Specifically, the first energy storage circuit 11 and the second energy storage circuit 12 are respectively used to couple with the power supply bus 101, so that when the first energy storage circuit 11 and / or the second energy storage circuit 12 are charged and stored with the electric energy on the power supply bus 101, or when the power supply bus 101 is fed and power compensated with the energy stored in the first energy storage circuit 11 and / or the second energy storage circuit 12, the output voltage of the power supply bus 101 can be effectively adjusted dynamically to ensure the stability of the output voltage of the power supply bus 101.

[0027] It is worth noting that the power supply bus 101 can be specifically understood as a main power supply line that utilizes the AC or DC input provided by an external AC or DC power supply, or performs power conversion and regulated AC or DC power output on a municipal power frequency power supply, a photovoltaic power supply, an independent generator or any other reasonable superior AC or DC power supply to supply power to the load circuit, so as to drive the load circuit to work.

[0028] In addition, the term "coupled" herein refers to any direct and indirect connection means. Therefore, if the first circuit is described as being coupled to the second circuit, it means that the first circuit can be directly connected to the second circuit through electrical connection or signal connection methods such as wireless transmission, optical transmission, etc., or can be indirectly connected to the second circuit through other circuits or connection means.

[0029] Among them, the first energy storage circuit 11 and the second energy storage circuit 12 are configured to have different terminal voltage change ratios when the same current flows through them, that is, when the current flowing through the first energy storage circuit 11 and the second energy storage circuit 12 is the same, the amplitude of the voltage increase or decrease at both ends of the two circuits is different, so that different voltage fluctuations can be caused in response to the same current change.

[0030] It is worth noting that the terminal voltage refers to the voltage between the corresponding two ends of a circuit connected to the outside; the terminal voltage change ratio can be understood as the ratio between the current voltage change amplitude and the initial voltage after the voltage change occurs, based on an initial voltage, which is used to characterize the magnitude of the current voltage fluctuation, that is, a larger terminal voltage change ratio corresponds to a larger voltage fluctuation, and a smaller terminal voltage change ratio corresponds to a smaller voltage fluctuation; and the terminal voltage change ratio of the first energy storage circuit 11 and the second energy storage circuit 12 when the same current flows through them is determined by their respective electrical and physical characteristics, and the present application does not limit this.

[0031] The electric energy conversion circuit 13 is coupled to the first energy storage circuit 11 and the second energy storage circuit 12. The electric energy conversion circuit 13 is used to use the electric energy on the power supply bus 101 to adjust the direction of electric energy transfer between the first energy storage circuit 11 and the second energy storage circuit 12, that is, to change the charging and energy storage direction between the first energy storage circuit 11 and the second energy storage circuit 12, thereby adjusting the output voltage of the power supply bus 101.

[0032] It is understandable that, in practical applications, when the power supply requires the voltage of the energy storage regulating circuit 10 to drop, the electric energy conversion circuit 13 can specifically control the voltage change ratio of the first energy storage circuit 11 and the second energy storage circuit 12 when the current flowing through the first energy storage circuit 11 and the second energy storage circuit 12 has the same current change, that is, the one with a larger voltage fluctuation transfers electric energy to the other with a smaller fluctuation. At this time, the voltage of one of the first energy storage circuit 11 and the second energy storage circuit 12 with a larger voltage fluctuation caused by the same current change will drop faster, while the voltage of the other of the first energy storage circuit 11 and the second energy storage circuit 12 with a smaller voltage fluctuation caused by the same current change will rise slower, thereby achieving an overall decrease in the output voltage of the power supply bus 101 connected in series with the energy storage regulating circuit 10.

[0033] On the contrary, when the power supply requires the voltage of the energy storage regulating circuit 10 to rise, the electric energy conversion circuit 13 can specifically control the other of the first energy storage circuit 11 and the second energy storage circuit 12 with smaller voltage fluctuation to transfer electric energy to the one with larger voltage fluctuation when the current flowing through the first energy storage circuit 11 and the second energy storage circuit 12 has the same current change. At this time, the voltage of one of the first energy storage circuit 11 and the second energy storage circuit 12 with larger voltage fluctuation caused by the same current change will rise faster, while the voltage of the other of the first energy storage circuit 11 and the second energy storage circuit 12 with smaller voltage fluctuation caused by the same current change will drop slower, thereby realizing an increase in the output voltage of the power supply bus 101 connected in series with the energy storage regulating circuit 10 as a whole.

[0034] The above scheme, by utilizing the different characteristics of voltage fluctuations caused by the first energy storage circuit 11 and the second energy storage circuit 12 under the same current change, effectively realizes dynamic adjustment of the output voltage of the power supply bus 101 when feeding energy to the power supply bus 101 or charging with the output voltage of the power supply bus 101, so as to ensure stable power supply, thereby obtaining better load characteristics and reducing unnecessary line and device losses; and the absorption effect of the energy fluctuation of the power supply bus 101 is strong, which effectively improves the power supply efficiency.

[0035] In some embodiments, the electric energy conversion circuit can specifically adjust the direction of electric energy transfer between the first energy storage circuit 11 and the second energy storage circuit 12 by controlling the switching state of the first energy storage circuit 11 and / or the second energy storage circuit 12, or it can receive an externally sent drive control signal and change its own switch state under the action of the drive control signal to adjust the direction of electric energy transfer between the first energy storage circuit and the second energy storage circuit. The specific direction is determined by the actual application scenario and is not limited in this application.

[0036] In some embodiments, the first energy storage circuit 11 may specifically include a collection of one or more devices in any reasonable circuit elements such as batteries, battery packs, capacitors, resistors, inductors, etc., which are connected in series and / or in parallel, and specifically corresponds to an energy storage circuit in which the terminal voltage changes in a smaller proportion when the current flowing through the second energy storage circuit 12 is the same, that is, the voltage fluctuation caused by the same current change is smaller; and the second energy storage circuit 12 may also specifically include a collection of one or more devices in any reasonable circuit elements such as batteries, battery packs, capacitors, resistors, inductors, etc., which are connected in series and / or in parallel, and specifically corresponds to an energy storage circuit in which the terminal voltage changes in a larger proportion when the current flowing through the first energy storage circuit 11 is the same, that is, the voltage fluctuation caused by the same current change is larger, which can be specifically determined by the actual application scenario, and the present application does not limit this.

[0037] In one embodiment, the number of the first energy storage circuits 11 may specifically be at least two, at least two first energy storage circuits 11 are coupled to the second energy storage circuits 12, and the power conversion circuit 13 is coupled to the second energy storage circuit 12 and at least one first energy storage circuit 11, so as to receive a drive control signal sent externally according to the current power supply demand, and change the switch state under the action of the drive control signal to adjust the direction of power transfer between the second energy storage circuit 12 and at least part of the first energy storage circuit 11 coupled thereto, that is, to change the charging and energy storage direction between the second energy storage circuit 12 and at least part of the first energy storage circuit 11 coupled thereto, so as to respond to different voltage fluctuations caused by the same current change, and effectively realize dynamic adjustment of the output voltage of the power supply bus 101 when feeding energy to the power supply bus 101 or charging with the output voltage of the power supply bus 101.

[0038] In another embodiment, the number of the second energy storage circuits 12 may be at least two, at least two second energy storage circuits 12 are coupled to the first energy storage circuit 11, and the power conversion circuit 13 is coupled to the first energy storage circuit 11 and at least one second energy storage circuit 12, so as to receive a drive control signal sent externally according to the current power supply demand, and change the switch state under the action of the drive control signal to adjust the direction of power transfer between the first energy storage circuit 11 and at least part of the second energy storage circuit 12 coupled thereto, that is, to change the charging and energy storage direction between the first energy storage circuit 11 and at least part of the second energy storage circuit 12 coupled thereto, so as to respond to different voltage fluctuations caused by the same current change, and effectively realize dynamic adjustment of the output voltage of the power supply bus 101 when feeding energy to the power supply bus 101 or charging using the output voltage of the power supply bus 101.

[0039] Please refer to Figure 2 , Figure 2 The energy storage regulating circuit in this embodiment differs from the first embodiment of the energy storage regulating circuit provided in this application in that the energy storage regulating circuit 20 specifically further includes a control circuit 24 .

[0040] Specifically, the power conversion circuit 23 further includes a first switch sub-circuit 231, a second switch sub-circuit 232 and a first inductor sub-circuit 233. The first inductor sub-circuit 233 couples the first energy storage circuit 21, the second energy storage circuit 22, the first switch sub-circuit 231 and the second switch sub-circuit 232. The first switch sub-circuit 231 couples the first energy storage circuit 21, the second switch sub-circuit 232 and the control circuit 24. The second switch sub-circuit 232 couples the second energy storage circuit 22 and the control circuit 24.

[0041] Among them, the drive control signal further includes a first control signal and a second control signal. The control circuit 24 is used to couple with the power supply bus 101, and / or the host computer, and / or the program burning device to obtain the output voltage on the power supply bus 101, and generate the first control signal and the second control signal based on the output voltage, and / or the program control signal input by the external host computer or the program burning device according to the current power supply demand, and / or a pre-set program control mode.

[0042] Furthermore, the control circuit 24 is also used to send a first control signal and a second control signal to the first switch subcircuit 231 and the second switch subcircuit 232 respectively, so as to trigger the first switch subcircuit 231 to be turned on and the second switch subcircuit 232 to be turned off in the first control mode, so as to utilize the first energy storage circuit 21 to store energy in the first inductor subcircuit 233, and after the energy storage continues for a preset period of time, trigger the first switch subcircuit 231 to be turned off, so as to utilize the current stored energy of the first inductor subcircuit 233 to store energy in the second energy storage circuit 22.

[0043] In some embodiments, the first control signal and the second control signal may specifically be one or more of any reasonable control signals such as a PWM (Pulse Width Modulation) signal or a PFM (Pulse Frequency Modulation) signal, and the present application does not limit this.

[0044] Among them, the control circuit 24 can specifically realize the corresponding on-off control of the first switch sub-circuit 231 and the second switch sub-circuit 232 by adjusting one or more of the parameters such as the duty cycle, signal frequency, dead time, etc. of the first control signal and the second control signal, and adjust the energy storage state between the first energy storage circuit 21 and the second energy storage circuit 22 by adjusting the preset time length.

[0045] Furthermore, because the first energy storage circuit 21 and the second energy storage circuit 22 are configured to have different terminal voltage change ratios when the same current flows through them, in the process of using the first energy storage circuit 21 to store energy in the first inductor sub-circuit 233, and using the current stored energy of the first inductor sub-circuit 233 to store energy in the second energy storage circuit 22, the output voltage of the power supply bus 101 will be increased or decreased as a whole, thereby being able to meet the current power supply demand.

[0046] Furthermore, the control circuit 24 is also used to trigger the second switch subcircuit 232 to be turned on using the second control signal in the second control mode, and simultaneously trigger the first switch subcircuit 231 to be turned off using the first control signal, so as to utilize the second energy storage circuit 22 to store energy in the first inductor subcircuit 233, and after the energy storage continues for a preset period of time, trigger the second switch subcircuit 232 to be turned off, so as to utilize the energy stored in the first inductor subcircuit 233 to store energy in the first energy storage circuit 21.

[0047] Please refer to Figure 3 , Figure 31 is a schematic diagram of the structure of the third embodiment of the energy storage regulation circuit of the present application. The difference between the energy storage regulation circuit in this embodiment and the first embodiment of the energy storage regulation circuit provided in the present application is that the power conversion circuit 33 in the energy storage regulation circuit 30 further includes a third switch sub-circuit 334, a fourth switch sub-circuit 335, a second inductor sub-circuit 336 and an isolation transformer 337.

[0048] The isolation transformer 337 further includes a coupled primary winding 3371 and a secondary winding 3372. The third switch sub-circuit 334 is coupled to the second energy storage circuit 32, the second inductor sub-circuit 336, the primary winding 3371 and the control circuit 34. The fourth switch sub-circuit 335 is coupled to the first energy storage circuit 31, the secondary winding 3372 and the control circuit 34. A first voltage regulating capacitor (not shown) is coupled between each first energy storage circuit 31 and the adjacent first energy storage circuit 31 or second energy storage circuit 32.

[0049] It is worth noting that the control circuit 34 can also send a third control signal and a fourth control signal to the third switch sub-circuit 334 and the fourth switch sub-circuit 335 respectively to trigger the third switch sub-circuit 334 to be turned on or off, and to trigger the fourth switch sub-circuit 335 to be turned on or off, so as to change the direction of power transfer between the second energy storage circuit 32 and the first energy storage circuit 31 respectively coupled to the third switch sub-circuit 334 and the fourth switch sub-circuit 335, thereby adjusting the output voltage of the power supply bus 101. For the specific control method, please refer to the control of the first switch sub-circuit 331 and the second switch sub-circuit 332 respectively, which will not be repeated here.

[0050] The isolation transformer 337 is used to achieve electrical isolation between the third switch sub-circuit 334 and the fourth switch sub-circuit 335 to avoid mutual interference between the two and affect the power supply stability.

[0051] In addition, the first voltage regulating capacitor is used to increase or decrease the output voltage of the power supply bus 101, wherein when the voltage of the first voltage regulating capacitor is positive, the output voltage of the power supply bus 101 is increased; and when the voltage of the first voltage regulating capacitor is negative, the output voltage of the power supply bus 101 is reduced.

[0052] In some embodiments, a second voltage regulating capacitor (not shown) is specifically coupled between the power supply bus 101 and the first energy storage circuit 31 or the second energy storage circuit 32 to increase or decrease the output voltage of the power supply bus 101 and to achieve voltage buffering isolation between the first energy storage circuit 31 or the second energy storage circuit 32 and the power supply bus 101 to prevent the output voltage of the power supply bus 101 from impacting the first energy storage circuit 31 or the second energy storage circuit 32.

[0053] In some embodiments, the first end of the third switch sub-circuit 334 and the first end of the fourth switch sub-circuit 335 are also coupled to an auxiliary capacitor (not shown) to provide capacity support for the third switch sub-circuit 334 and the first voltage regulating capacitor connected in parallel therewith, and can also achieve auxiliary filtering.

[0054] The first end of the third switch sub-circuit 334 can be specifically utilized as an end far away from the fourth switch sub-circuit 335 , and the first end of the fourth switch sub-circuit 335 is an end close to the third switch sub-circuit 334 .

[0055] In some other embodiments, the power conversion circuit 33 may specifically include only the third switch sub-circuit 334, the fourth switch sub-circuit 335, the second inductor sub-circuit 336, the isolation transformer 337, and the first energy storage circuit 31 and the second energy storage circuit 32 respectively connected to the third switch sub-circuit 334 and the fourth switch sub-circuit 335, but does not include the first switch sub-circuit 331 and the second switch sub-circuit 332 and the first energy storage circuit 31 and the second energy storage circuit 32 respectively connected thereto; and the number of the third switch sub-circuit 334, the fourth switch sub-circuit 335, the second inductor sub-circuit 336, and the isolation transformer 337 may specifically be at least two, and is determined by the actual application scenario, and the present application does not limit this.

[0056] Please refer to Figure 4a , Figure 4a 1 is a schematic diagram of the structure of the fourth embodiment of the energy storage regulation circuit of the present application. The difference between the energy storage regulation circuit in this embodiment and the second embodiment of the energy storage regulation circuit provided in the present application is that the first inductor subcircuit 433 in the energy storage regulation circuit 40 further includes a first inductor Lr1, the first switch subcircuit 431 includes a first switch tube Q1, and the second switch subcircuit 432 includes a second switch tube Q2.

[0057] Among them, the first end of the first energy storage circuit 41 is coupled to the second end of the first switch tube Q1, and is used to couple the first end of the power supply bus 101, the second end of the first energy storage circuit 41 is coupled to the first end of the second energy storage circuit 42 and the first end of the first inductor Lr1, the second end of the first inductor Lr1 is coupled to the third end of the first switch tube Q1 and the second end of the second switch tube Q2, the second end of the second energy storage circuit 42 is coupled to the third end of the second switch tube Q2, and is used to couple the second end of the power supply bus 101, and the first end of the first switch tube Q1 and the first end of the second switch tube Q2 are coupled to the control circuit (not shown in the figure).

[0058] In some embodiments, the first switch tube Q1 and the second switch tube Q2 can specifically be a MOS (Metal Oxide Semiconductor Field Effect Transistor) tube, a triode, a thin film transistor or a field effect transistor or any other reasonable switch tube, which is not limited in the present application.

[0059] It is worth noting that, in order to distinguish the two ends of each switch tube except the control end, one of them is called the second end and the other is called the third end. When each switch tube is a triode, the control end, that is, the first end, can be specifically the base, the second end is the collector, and the third end is the emitter; or, the first end can also be specifically the base, the second end is the emitter, and the third end is the collector.

[0060] When the above switch tubes are MOS tubes, thin film transistors or field effect transistors, the first end can be a gate, the second end can be a drain, and the third end can be a source; or, the first end can be a gate, the second end can be a source, and the third end can be a drain.

[0061] When each switch tube is a MOS tube, a thin film transistor or a field effect transistor, it can also be a composite transistor or a single transistor, which is not limited in the present application.

[0062] Please continue to refer to Figure 4b and Figure 4c ,in, Figure 4b and Figure 4c yes Figure 4a A structural diagram of the energy storage transfer direction of the energy storage regulating circuit 40 in the first control mode.

[0063] For ease of understanding, the first energy storage circuit 41 includes a battery pack Bt1, and the second energy storage circuit 42 includes an energy storage capacitor C1. It can be seen that the battery pack Bt1 has the characteristic of smaller voltage fluctuation caused by the same current change; while the energy storage capacitor C1 has the characteristic of larger voltage fluctuation caused by the same current change.

[0064] The first switch tube Q1 , the second switch tube Q2 , and the first inductor Lr1 serve as switch devices and switch energy storage inductors of the power conversion circuit 43 .

[0065] The battery pack Bt1 and the energy storage capacitor C1 are connected in series and then directly connected to the power supply bus 101 to absorb the energy fluctuation of the power supply bus 101 with low impedance.

[0066] The control strategy of the control circuit to adjust the output voltage Vo of the power supply bus 101 is as follows: like Figure 4bAs shown, the first switch tube Q1 is triggered to turn on, and the second switch tube Q2 is triggered to turn off at the same time, and the battery pack Bt1 stores energy in the first inductor Lr1 accordingly; like Figure 4c As shown, the first switch tube Q1 is triggered to turn off, and the energy in the first inductor Lr1 is stored in the energy storage capacitor C1 through the second switch tube Q2. At this time, the second switch tube Q2 can be triggered to turn on or off, so as to use the freewheeling diode inside the second switch tube Q2 to store energy in the energy storage capacitor C1.

[0067] It is understandable that the energy storage current I L After flowing out of the battery pack Bt1 and into the energy storage capacitor C1, the voltage V1 across the battery pack Bt1 will drop slightly, and the voltage V2 across the energy storage capacitor C1 will rise significantly. The output voltage Vo of the power supply bus 101, which is the superposition of the voltage V1 across the battery pack Bt1 and the voltage V2 across the energy storage capacitor C1, will rise.

[0069] The control strategy of the control circuit to adjust the output voltage Vo of the power supply bus 101 to decrease is as follows: like Figure 4d As shown, the second switch tube Q2 is triggered to turn on, and the first switch tube Q1 is triggered to turn off at the same time, and the energy storage capacitor C1 stores energy in the first inductor Lr1 accordingly; like Figure 4e As shown, the second switch tube Q2 is triggered to turn off, and the energy in the first inductor Lr1 is stored in the battery pack Bt1 through the first switch tube Q1. At this time, the first switch tube Q1 can be triggered to turn on or off, so as to use the freewheeling diode inside the first switch tube Q1 to store energy in the battery pack Bt1.

[0070] It is understandable that the energy storage current I L After flowing out of the energy storage capacitor C1 and into the battery pack Bt1, the voltage V1 across the battery pack Bt1 will rise slightly, and the voltage V2 across the energy storage capacitor C1 will drop significantly. The output voltage Vo of the power supply bus 101, which is the superposition of the voltage V1 across the battery pack Bt1 and the voltage V2 across the energy storage capacitor C1, will drop.
