[0002] In existing technologies, power modules are one of the key semiconductor modules in vehicle control systems. Power modules can be used for at least electrical energy conversion.

[0003] In existing power modules, multiple signal terminals connected to the power control circuit are typically located around the perimeter of the power control circuit. For design convenience, existing signal terminals are numerous and varied, widely distributed, and spaced far apart.

Any embodiment or design that is described as "as an example" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design options.

[0059] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.
[0060] New energy vehicles include electric drive systems, which use electricity to propel the vehicle. Taking range-extended electric vehicles as an example, their topology is as follows: Figure 1 As shown. The core component is the range extender 07, whose main function is to activate the range extender 07 when the power battery 03's charge drops to a certain level, causing the engine 04 to drive the generator M2 to generate electricity. Part of the generated electricity can be used to power the drive motor M1, and the other part can be used to charge the power battery 03. An inverter 06 is also installed between the drive motor M1 and the power battery 03.
[0061] Range-extended electric vehicles (REEVs) offer numerous advantages, including: During daily urban commutes, they can operate on pure electric power with zero emissions, reducing exhaust pollution and meeting environmental protection requirements. Furthermore, electric drive is more energy-efficient than gasoline drive, lowering energy consumption and operating costs.
[0062] Range-extended electric vehicles are equipped with an engine 04 as a range extender 07. When the battery is low, the engine can start to generate electricity to provide continuous power to the vehicle, avoiding the range anxiety problem caused by the limited driving range of pure electric vehicles and making long-distance travel more convenient.
[0063] In addition, range-extended electric vehicles also have the following advantages in terms of driving experience:
[0064] Pure electric drive: The range-extended topology is essentially a pure electric drive system. The vehicle's driving power is entirely provided by the electric motor (i.e., drive motor M1). The engine 04 does not directly participate in driving the vehicle, but plays the role of generating electricity. It starts when the power battery 03 is low on power, converting fuel into electrical energy to power drive motor M1 or charge power battery 03. This pure electric drive method makes the vehicle's power source single and pure, consistent with the driving method of pure electric vehicles, fundamentally ensuring the comfort of the driving experience.
[0065] Rapid power response: The characteristics of the drive motor M1 enable it to output maximum torque instantly. In range-extended electric vehicles, when the driver presses the accelerator pedal, the drive motor M1 responds immediately, rapidly delivering powerful output for quick starts and acceleration. This instantaneous power response is far superior to traditional gasoline vehicles, allowing the driver to experience a more direct and rapid surge of power. Whether in the frequent stop-and-go traffic of city driving or overtaking maneuvers on highways, it handles everything with ease, delivering a smooth driving experience.
[0066] No power interruption: During the operation of a range-extended vehicle, since it is always driven by the drive motor M1, there is no power interruption problem as seen in traditional gasoline vehicles when shifting gears. Whether driving at low or high speeds, the power output remains continuous and smooth. Even when the power battery 03 is low on charge and the engine 04 starts generating electricity, the system can ensure that the power output of the drive motor M1 is unaffected through precise control strategies, without any jerking or power interruption. This provides the driver with a consistently stable driving experience, improving driving comfort and safety.
[0067] However, in existing technologies, the electric drive assembly of range-extended electric vehicles includes components such as generator M2, drive motor M1, generator controller, and drive motor controller. Figure 1The motor controller 05 shown includes a generator controller and a drive motor controller. The generator controller and drive motor controller are independent components, each with its own power supply (e.g., using diodes, IGBTs, SiC semiconductors for AC-DC conversion), current sensors, temperature sensors, motor rotor position sensors, and other sensors. Their weight, size, and cost are all relatively high, necessitating optimization.
[0068] Figure 2 This diagram illustrates the topology of the drive module and power generation module in an existing range-extended electric vehicle. (See also...) Figure 2 The drive module converts the DC power from the high-voltage battery into AC power to drive the drive motor M1, providing torque to rotate the wheels. The generator module converts the AC power output from the generator M2 into DC power to charge the high-voltage power battery 03 or to power the drive motor M1.
[0069] As mentioned earlier, with the development of the new energy vehicle industry, market competition is becoming increasingly fierce, and the pressure to control costs is also increasing. As a crucial component of the vehicle, optimizing the electronic control system from multiple aspects, including cost, space utilization, and performance, has become a widely discussed issue.
[0070] In the electronic control assembly, current sensors are needed to monitor the magnitude and direction of the current in the power module. On the one hand, when abnormalities such as overcurrent occur, protection mechanisms can be triggered to prevent damage to the power module or other critical components. On the other hand, the operating state of the power module can be adjusted based on the real-time current data provided by the autonomous current sensor to ensure the stability of the output.
[0071] In traditional solutions, current sensors typically exist as a separate component, including a magnetic core, coil, and other related parts. These components often require additional mounting and fixing devices such as plastic coating and screws to ensure their stability and safety. Not only does the complex assembly process lead to increased labor costs, but the materials required for each individual current sensor and its installation, such as plastic coating materials and fasteners, also increase manufacturing costs.
[0072] On the other hand, in order to meet the requirements of mechanical strength and electrical isolation, the overall structure of a standalone current sensor is usually bulky and occupies a lot of space, which is a significant disadvantage in applications with strict space requirements, such as new energy vehicles.
[0073] In addition, each current sensor requires a long connecting cable to connect to the power module, which can easily introduce electromagnetic interference and affect the stability and accuracy of the electronic control assembly.
[0074] Figure 3 The diagram shows the terminal layout design of a traditional power module. (Example:) Figure 3 As shown, in the prior art, the drive module and the power generation module adopt three independent half-bridge circuits, and the signal terminals are arranged along the substrate edge of each half-bridge circuit. Refer to Figure 3 , the gate signal terminal G1, the emitter signal terminal E1, and the collector signal terminal C1 are used to transmit the upper-bridge drive signal of the U phase of the drive module; the gate signal terminal G2, the emitter signal terminal E2, and the collector signal terminal C2 are used to transmit the lower-bridge drive signal of the U phase of the drive module; the gate signal terminal G3, the emitter signal terminal E3, and the collector signal terminal C3 are used to transmit the lower-bridge drive signal of the V phase of the drive module; the gate signal terminal G4, the emitter signal terminal E4, and the collector signal terminal C4 are used to transmit the lower-bridge drive signal of the V phase of the drive module; the gate signal terminal G5, the emitter signal terminal E5, and the collector signal terminal C5 are used to transmit the lower-bridge drive signal of the W phase of the drive module; the gate signal terminal G6, the emitter signal terminal E6, and the collector signal terminal C6 are used to transmit the lower-bridge drive signal of the W phase of the drive module; the temperature measurement signal terminals T1 and the temperature measurement signal terminal T2 are used to transmit the signals of the U-phase temperature measurement resistor; the temperature measurement signal terminals T3 and the temperature measurement signal terminal T4 are used to transmit the signals of the V-phase temperature measurement resistor; the temperature measurement signal terminals T5 and the temperature measurement signal terminal T6 are used to transmit the signals of the W-phase temperature measurement resistor. At least 8 signal terminals are required in each half-bridge unit, and at least 24 signal terminals are required for the drive module or the power generation module. To ensure the electrical safety of the devices in the control circuit supporting the power module, it is necessary to ensure sufficient spacing between the signal terminals to reserve enough clearance distance for installing the devices of the control circuit. Therefore, on the one hand, the size of the independent traditional power module is large. On the other hand, its signal pin types are comprehensive and numerous, and the distribution divergence and spacing are large. When adapting to the PCB design, more clearance intervals need to be considered to meet the restrictions of safety specifications (such as GB / T16935.1-2008), resulting in an increase in the design size of the adapted PCB. Thus, it is not conducive to the requirement of overall miniaturization of the module.
[0075] To solve the above technical problems, the present application provides a power module group, including a drive power module 100, and the drive power module 100 includes at least two first bridge arms arranged along the first direction,. The first bridge arm includes an upper-bridge arm circuit and a lower-bridge arm circuit, and the upper-bridge arm circuit and the lower-bridge arm circuit include power semiconductors.
[0076] The drive power module 100 may further include a first substrate, and the first bridge arm is arranged on the first substrate. It may be that each first substrate is provided with a half-bridge circuit to form an inverter bridge or a rectifier bridge. The first bridge arm is the half-bridge circuit, and each half-bridge circuit corresponds to one phase of the current passing through the half-bridge circuit.
[0077] In the embodiment of the present application, as Figure 4As shown, the first direction is parallel to the power module's liner structure and is arranged along the arrangement direction of the first bridge arm; the second direction is parallel to the power module's liner structure. That is, the second direction is parallel to the surface of the first liner, just like the first direction. The second direction is perpendicular to the first direction.
[0078] Each first bridge arm further includes a first terminal group 101 and a second terminal group 102, respectively used to transmit signals from the upper bridge arm circuit and the lower bridge arm circuit in the corresponding phase. The first terminal group 101 is used to transmit the emitter signal, gate signal, and collector signal of the power semiconductor in the upper bridge arm circuit; the second terminal group 102 is used to transmit the emitter signal and gate signal of the power semiconductor in the lower bridge arm circuit. In embodiments of this application, the power module includes a PCB board adapted to the first bridge arm of the driving power module. Electronic components are disposed on the PCB board, and through-holes are provided between the electronic components. The terminals on the driving power module correspond one-to-one with the positions of the through-holes and pass through the through-holes. Therefore, by optimizing the terminal layout, the terminals have a more compact layout structure, thereby reducing the corresponding PCB board size.
[0079] In an optional embodiment, the first terminal group 101 includes a plurality of terminals: a first emitter terminal electrically connected to the emitter of a power semiconductor in the upper bridge arm circuit, a first gate terminal electrically connected to the gate of a power semiconductor in the upper bridge arm circuit, and a first collector terminal electrically connected to the collector of a power semiconductor in the upper bridge arm circuit, wherein the first emitter terminal, the first gate terminal, and the first collector terminal are arranged along a second direction. The second terminal group 102 includes a plurality of terminals: a second emitter terminal electrically connected to the emitter of a power semiconductor in the lower bridge arm circuit, and a second gate terminal electrically connected to the gate of a power semiconductor in the lower bridge arm circuit, wherein the second emitter terminal and the second gate terminal are arranged along a second direction.
[0080] Since the collector of the power semiconductor in the lower bridge arm circuit of the first bridge arm in this embodiment is shared with the emitter of the power semiconductor in the upper bridge, the second terminal group may not have a collector terminal. Therefore, the collector signal transmission of the power semiconductor in the lower bridge circuit is omitted in the second terminal group 102, and the second terminal group may also include a collector terminal.
[0081] The first terminal group 101 and the second terminal group 102 are arranged along the second direction on the drive power module. Compared with the prior art, where the upper bridge arm signal terminals and the lower bridge arm signal terminals are arranged relatively dispersedly along the first direction on the edge of the substrate structure, the arrangement structure of the signal terminals is changed, making the layout of the signal terminals more concentrated, compact and non-dispersed, and reserving sufficient space for the layout of the circuit board.
[0082] Compared to traditional technologies that use multiple types of signal terminals, the embodiments of this application reduce the number of terminals in the drive power module by simplifying terminal types and using shared terminals. This reduces the area occupied by the through holes on the corresponding PCB board while meeting the installation specification clearance requirements, thereby helping to reduce the size of the adapter PCB board.
[0083] In an optional embodiment, the first terminal group 101 and the second terminal group 102 are arranged along a second direction and disposed in the middle portion of the first substrate in a first direction. Compared to the conventional technology that arranges terminals around the perimeter of the half-bridge circuit, this layout arranges the terminals in the middle portion of the first bridge arm, reserving mounting space for chips on both sides, resulting in a more compact terminal arrangement. Furthermore, by reducing the number of terminals, the terminal arrangement in the drive power module 100 can be made more compact, thereby reducing the corresponding PCB board size. Simultaneously, the more compact terminal arrangement also helps ensure sufficient distance between the vias on the PCB board and the PCB board itself, facilitating the placement of components and the installation of the PCB board.
[0084] The drive power module 100 may also include a first thermistor and a third terminal group 103. The third terminal group 103 is electrically connected to the first thermistor, which measures the temperature of the first liner of the first bridge arm of the corresponding phase and outputs the signal through the third terminal group 103. Specifically, the third terminal group 103 includes two third terminals connected to the two ends of the first thermistor. The third terminal group 103, the first terminal group 101, and the second terminal group 102 are arranged along a second direction on the first bridge arm.
[0085] In an optional embodiment, a first thermistor and a third terminal group 103 are provided on the first liner corresponding to one phase of the multi-phase first bridge arm. Temperature is measured using only one thermistor, reducing the number of terminals. For example, the power module also includes a power generation module 200, and the drive power module 100 includes at least two first bridge arms, each with an independent first liner. The third terminal group 103 is disposed on the first liner closest to the power generation module 200. The power module is equipped with a cooling device, and the coolant can flow from the drive power module 100 to the power generation module 200. The temperature of the first liner closest to the power generation module 200 is the highest temperature of the drive power module 100. Considering cost reduction, only detecting the highest temperature of the drive power module 100 can ensure the normal operation of the solution.
[0086] In an optional embodiment, each first arm of the drive power module 100 is provided with a first thermistor and a third terminal group 103.
[0087] In an optional embodiment, the third terminal group 103 is disposed in the second direction between the first terminal group 101 and the second terminal group 102 of the first bridge arm, which also facilitates leaving space on both sides of the first bridge arm. The third terminal group 103 includes at least two third terminals, which are arranged along the first direction. The two third terminals are arranged horizontally along the first direction, which can save height space in the second direction.
[0088] In an optional embodiment, the power module includes an integrated drive power module 100 and a power generation module 200. Through-holes on the PCB correspond one-to-one with the positions of terminals on the drive power module 100 and the power generation module 200. The power generation module 200 includes a second bridge arm and a second substrate, with at least two second bridge arms disposed on the same second substrate. For example, the second substrate may be configured with an inverter full-bridge circuit or a rectifier full-bridge circuit, the number of phases of the full-bridge circuit corresponding to the number of current phases flowing through the power generation module 200. The full-bridge circuit includes an upper bridge arm circuit and a lower bridge arm circuit, both of which include power semiconductors. The power module provided in this application employs a combined drive power module 100 and power generation module 200 design, thereby compressing the total PCB area and reducing the PCB area by more than 40%.
[0089] The power generation module 200 includes a fourth terminal group 201 and a fifth terminal group 202, which are used to transmit the emitter and gate signals of the power semiconductor in the upper bridge arm circuit and the emitter and gate signals of the power semiconductor in the lower bridge arm circuit, respectively. Specifically, the fourth terminal group 201 is electrically connected to the emitter and gate of the upper bridge arm circuit of the second bridge arm, and the fifth terminal group 202 is electrically connected to the emitter and gate of the lower bridge arm circuit of the second bridge arm. The power generation module 200 also includes a seventh terminal 204, used to transmit the collector signal of the power semiconductor in either the upper or lower bridge arm circuit. Specifically, the seventh terminal 204 is electrically connected to the collector of the upper bridge arm circuit of the second bridge arm, and the collector terminals of the upper bridge arm circuit are shared.
[0090] The power generation module 200 also includes a second thermistor and a sixth terminal group 203. The sixth terminal group 203 includes two sixth terminals, which are respectively connected to the two ends of the second thermistor. The second thermistor is used to measure the temperature of the second liner structure of the second bridge arm of the corresponding phase and outputs the signal through the sixth terminal group 203. The use of a full-bridge circuit in the power generation module 200 allows the power generation module 200 to be integrated onto the same second liner, further reducing the number of temperature sensing resistors, thereby reducing the number of temperature sensing signal terminals and reducing the layout space required for the temperature sensing signal terminals.
[0091] In an optional embodiment, the first and second substrates include a heat dissipation device and a copper-clad ceramic plate. The heat dissipation device may include heat dissipation fins, and the copper-clad ceramic plate includes a ceramic substrate and a copper-clad layer on the surface of the ceramic substrate. The copper-clad ceramic plate is fixed to the heat dissipation device by soldering; each power semiconductor is fixed to the surface of the copper-clad ceramic plate opposite to the heat dissipation device by soldering, and each terminal group is fixed to the surface of the copper-clad ceramic plate opposite to the heat dissipation device.
[0092] In an optional embodiment, the first thermistor and the second thermistor include NTC resistors (Negative Temperature Coefficient Thermistors), which are semiconductor devices whose resistance decreases significantly with increasing temperature and are widely used in temperature sensing, surge current suppression, temperature compensation and other scenarios.
[0093] In an optional embodiment, the fourth terminal group 201 includes fourth terminal pairs corresponding to the number of current phases through the second bridge arm. Each fourth terminal pair includes a fourth emitter terminal and a fourth gate terminal, the fourth emitter terminal being connected to the emitter of the power semiconductor of the corresponding phase in the upper bridge arm circuit, and the fourth gate terminal being connected to the gate of the power semiconductor of the corresponding phase in the upper bridge circuit. The fifth terminal group 202 includes fifth terminal pairs corresponding to the number of current phases through the power generation module. Each fifth terminal pair includes a fifth emitter terminal and a fifth gate terminal, the fifth emitter terminal being connected to the emitter of the power semiconductor of the corresponding phase in the lower bridge arm circuit, and the fifth gate terminal being connected to the gate of the power semiconductor of the corresponding phase in the lower bridge arm circuit. The sixth terminal group 203 includes two sixth terminals connected to the two ends of the second thermistor. The seventh terminal 204 is connected to the collector of the power semiconductor in the upper bridge arm circuit.
[0094] In an optional embodiment, the fifth terminal group 202 includes a fifth gate terminal corresponding to the number of current phases through the second bridge arm and a fifth emitter terminal. The fifth gate terminal is connected to the gate of the power semiconductor of the corresponding phase in the lower bridge arm circuit, and the fifth emitter terminal is connected to the common emitter of the power semiconductors of all phases in the lower bridge arm circuit. This can further reduce the number of terminals and facilitate the arrangement of the terminals.
[0095] In an optional embodiment, the fourth terminal group 201 and the seventh terminal group 204 are arranged along a first direction in the region near the first side of the second substrate, the fifth terminal group 202 is arranged along a first direction in the region near the second side of the second substrate structure, the sixth terminal group 203 is arranged along a second direction in the region near the third side of the second substrate, and the seventh terminal 204 is disposed in the region near the third side of the second substrate. In the embodiments of this application, the first side and the second side of the second substrate are opposite to each other in the second direction, and the first side is located in the second direction of the second side; the third side and the fourth side are opposite to each other in the first direction and are adjacent to the first side and the second side, and the third side is located in the first direction of the fourth side. The chip area of the power generation module 200 is relatively large, so that its terminals are arranged at the edge of the second substrate, leaving an installation area in the middle, which is beneficial to reserve sufficient space for high-voltage devices in the middle for the adaptation PCB.

[0103] In an optional embodiment, a first clearance distance 110 is formed between the two terminals with the largest distance in the second direction on the same first bridge arm. The minimum dimension of the first clearance distance 110 in the second direction is 46mm, which helps to meet the chip mounting size requirements in the power generation module 200. That is, it helps to ensure that the terminals on the drive power module maintain sufficient distance, thereby avoiding large interference between the terminals, and at the same time helps to ensure that the PCB board has sufficient reserved space in the second direction.
[0104] In an optional embodiment, two adjacent first bridge arms form a second clearance distance 120 between them in the first direction, the second clearance distance 120 having a maximum dimension of 30mm in the first direction. This helps ensure that the terminals on the drive power module are located in the middle of the first backing plate, thereby avoiding insufficient reserved space for the adapter PCB. It also helps control the total length of multiple drive power modules in the first direction, facilitating the miniaturization design of the power modules.
[0105] In an optional embodiment, a third clearance distance 130 is formed between the fourth terminal group 201 and the fifth terminal group 202, the minimum dimension of the third clearance distance 130 in the second direction being 46 mm.

The fourth clearance distance 140 has a minimum dimension of 64mm in the first direction, which meets the chip mounting size requirements in the power generation module 200. This helps ensure sufficient space for the adapter PCB in the first direction, and also helps ensure sufficient distance between the terminals on the power generation module 200, thereby avoiding significant interference between the terminals.
[0107] Further integration Figure 5 This application describes a terminal layout in a power module according to an embodiment. For example... Figure 5 As shown, in the U, V, and W phases of the drive power module, a first clearance distance 110 is formed between the terminals E1 and E2, E3 and E4, and E5 and E6 that are furthest apart in the second direction, with a distance of at least 46 mm in the second direction. A second clearance distance 120 is formed between the terminals T2 and T3, and T4 and T5 that are closest together in the first direction between the U and V phases, and between the V and W phases, with a distance of at most 30 mm in the first direction. On the power generation module 200, a third clearance distance 130 is formed between two sets of terminals in the second direction, with a distance of at least 46 mm in the second direction. A fourth clearance distance 140 is formed between the terminal T6, which is closest to the power generation module 200 in the first direction, and the terminal in the area of the power generation module 200 near the third side of the second liner, with a distance of at least 64 mm between them in the first direction.
[0108] In the embodiments of this application, the first terminal group 101 and the second terminal group 102 are arranged along the second direction. It is not required that the two terminal groups are aligned along a straight line parallel to the second direction. They can also be staggered by a certain distance, as long as the first terminal group 101 and the second terminal group 102 are arranged along the second direction as a whole.
[0109] Can be combined Figures 6 to 10 understand, Figures 6 to 10 The diagram illustrates five different arrangements of the first terminal group 101 and the second terminal group 102 of the first bridge arm. The first bridge arm includes IGBT (Insulated-Gate Bipolar Transistor) and FRD (Fast Recovery Diode).
[0110] Figure 6 The first terminal group 101 and the second terminal group 102, as shown, are located in the middle portion of the first bridge arm along the first direction, and are aligned along the second direction. Figure 4 The arrangement corresponds to the layout in the text.
[0111] Figure 7 The upper and lower bridge arm circuits shown are offset in the second direction. At this time, the first terminal group 101 is arranged in the middle part of the upper bridge arm circuit, and the second terminal group 102 is arranged in the middle part of the lower bridge arm circuit. Although the first terminal group 101 and the second terminal group 102 are distributed along the second direction, they are offset in the second direction.
[0112] Figure 8 and Figure 7 The structure is similar, only Figure 7 The upper bridge arm circuit is offset to the left relative to the lower bridge arm circuit. Figure 8 The upper bridge circuit arm is deflected to the right relative to the lower bridge circuit arm. Figure 7 , 8 The left and right directions in the middle are also the first direction.
[0113] Figure 9 In the first terminal group 101 and the second terminal group 102 are not located in the middle part of the first bridge arm, but are located on different sides of the first bridge arm along the first direction. Specifically, the first terminal group 101 is located on the right side of the upper bridge arm circuit, and the second terminal group 102 is located on the left side of the lower bridge arm circuit.
[0114] Figure 10 In the first terminal group 101 and the second terminal group 102 are respectively disposed on different sides of the first bridge arm along the first direction. Specifically, the first terminal group 101 is disposed on the left side of the upper bridge arm circuit, and the second terminal group 102 is disposed on the right side of the lower bridge arm circuit.
[0115] As can be seen, the positions of the first terminal group 101 and the second terminal group 102 can be arranged according to actual needs, and the first terminal group 101 and the second terminal group 102 can be arranged along the second direction.
[0116] Let's look again. Figure 11 and Figure 12, Figure 11 The diagram illustrates the arrangement direction of the two third terminals of the third terminal group 103, which is arranged along the first direction. Figure 4 The arrangement corresponds to the layout in the text. Figure 12 The diagram illustrates that the two third terminals of the third terminal group 103 are arranged along the second direction. That is, the arrangement direction of the third terminal group 103 can be either the first direction or the second direction.

[0119] Furthermore, this application also provides a vehicle including the electronic control assembly described above.
[0120] Compared to the prior art where signal terminals are arranged along the edge of the substrate, the power module provided in this application concentrates the first terminal group 101, second terminal group 102, and third terminal group 103 of the first bridge arm of the driving power module 100 in the middle of each first bridge arm, reducing the space occupied by the signal terminal group. This allows for sufficient clearance between signal terminals in adjacent phases. Simultaneously, since the signal terminals are arranged along the central axis, excessive redundant space on both sides of the substrate structure is avoided, shortening the distance between adjacent sub-circuits and reducing the area of the compatible PCB board. Based on the above embodiments, by optimizing the terminal layout in the driving power module 100 and the power generation module 200, the number of signal pins is reduced and the layout is more compact. This allows for sufficient clearance on the compatible PCB board for mounting control circuit devices, while meeting electrical clearance requirements stipulated by safety regulations and reducing the overlap area with power semiconductors in the power module. Meanwhile, with the integration of the drive power module 100 and the power generation module 200, the PCB area corresponding to the power module is further reduced, which is conducive to reducing the size of the two-in-one power module that integrates the drive power module 100 and the power generation module 200, and can realize the miniaturization design of the power module.
