[0032] Embodiments of the present application are described in detail below with reference to the accompanying drawings, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0033] The integrated power module, the compressor controller, the compressor and the vehicle of the embodiments of the present application are described below with reference to the accompanying drawings.

[0034] Figure 1 A structural schematic diagram of a PTC heater in the related art is shown, as shown in Figure 1 The PTC heater 300 includes a heater controller 310 and a heating unit 320, wherein the heater controller 310 includes a first voltage conversion unit 311 and a first control unit 312, a first isolation voltage conversion unit 313, an isolation driving unit 314 and a switching unit 315 arranged in a low-voltage area 2000, and the heating unit 320 includes two groups of PTC resistors 321, wherein the switching unit 315 includes two switching tubes QA and QB, each switching tube is connected with a group of PTC resistors PTC, and each group of PTC resistors 321 includes three PTC resistors PTC connected in parallel.

[0035] Figure 2 A structural schematic diagram of a compressor controller in the related art is shown, as shown in Figure 2 The compressor controller 100 includes a voltage conversion unit 10 and a receiving unit 20, an isolation voltage conversion unit 30, an isolation communication unit 40 arranged in a low-voltage area 2000, a first driving unit 50, a control unit 60 and an inverter circuit 70 arranged in a high-voltage area 1000, wherein the inverter circuit 70 is adapted to be connected with a compressor motor 210, and the inverter circuit 70 includes six switching tubes Q1-Q6, and the six switching tubes Q1-Q6 constitute three-phase bridge arms to drive the compressor motor 210.

[0036] Figure 3 An external connection mode of a compressor and a PTC heater in the related art is shown, as shown in Figure 3 The compressor 200 includes a compressor motor 210 and a compressor controller 100, and the PTC heater 300 includes a heater controller 310 and a heating unit 320, and the compressor controller 100 and the heater controller 310 both need to be connected with a high-voltage power supply unit 400, a low-voltage power supply unit 500 and a CAN (Controller Area Network) bus 600.

[0037] From Figures 1 to 3As can be seen, the heater controller 310 and the compressor controller 100 have similar circuits, so the voltage conversion unit 10, the receiving unit 20, the isolation transformer unit 30, the isolation communication unit 40 and the control unit 60 in the compressor controller 100 can be reused, and the second driving unit 80 and the switching circuit 90 are added in the compressor controller 100 to form the compressor controller 100 as shown in Figure 4 The PTC heater 300 can be integrated in the compressor controller 100, which can significantly reduce the volume of the PTC heater 300. However, the second driving unit 80 and the switching circuit 90 are added in the compressor controller 100, which increases the volume of the compressor controller 100 and the volume of the compressor 200.

[0038] Figure 5 The integrated power module 101 is applied to the compressor controller 100 as shown in Figure 4 The integrated power module 101 includes a board body (not shown) and an inverter circuit 70 and a switching circuit 90 arranged on the board body, as shown in Figure 5

[0039] The inverter circuit 70 is configured to control the compressor motor 210 based on the received first driving control signal, and the switching circuit 90 is configured to control the PTC heater 300 based on the received second driving control signal, wherein the first driving control signal and the second driving control signal are generated based on the control instruction output by the control unit 60.

[0040] Specifically, as shown in Figure 5 The inverter circuit 70 includes six switching tubes Q1-Q6 to control the compressor motor 210 according to the first driving control signal, and the switching circuit 90 includes two switching tubes QA and QB to control the PTC heater 300 according to the second driving signal. Because the inverter circuit 70 and the switching circuit 90 are integrated on the board body, the newly added switching circuit 90 in the compressor controller 100 does not occupy additional space and does not increase the size of the compressor controller 100, and the integrated power module 101 can be applied to various types of compressors, thereby improving the versatility of the compressor controller 100.

[0041] Further, because the PTC heater 300 and the compressor 200 usually do not work at the same time, the inverter circuit 70 and the switching circuit 90 also do not work at the same time, so the inverter circuit 70 and the switching circuit 90 can share the heat dissipation surface (not shown) of the integrated power module 101 in time, which not only reduces the heat dissipation surface of the integrated power module 101, but also is conducive to heat dissipation design.​

[0042] It should be noted that the inverter circuit 70 is not limited to the one described above. Figure 5 The three-phase inverter circuit shown can also be used for other inverter circuits 70. The switching circuit 90 is also not as... Figure 5 The two switching transistors QA and QB shown can also be one or more. Figure 5 The inverter circuit 70 and the switching circuit 90 in the diagram are exemplary and are not intended to limit the scope of this application.

[0043] In the above embodiments, the inverter circuit and the switching circuit are integrated into the integrated power module of the compressor controller, which enables the compressor controller to control the PTC heater and the compressor motor. This eliminates the need for the PTC controller in the PTC heater. Furthermore, since the inverter circuit and the switching circuit are integrated together, the size of the compressor controller is not increased, thereby reducing the size and cost of the vehicle air conditioning system. In addition, the inverter circuit and the switching circuit can share a heat dissipation surface, which is beneficial to the heat dissipation design of the integrated power module.

[0044] In some embodiments, such as Figure 6 As shown, a drive signal receiving end is provided on the board. The drive signal receiving end is connected to the inverter circuit 70 and the switching circuit 90 respectively, so as to send the received first drive control signal and second drive control signal to the inverter circuit 70 and the switching circuit 90 respectively.

[0045] Specifically, the compressor controller 100 further includes a drive unit 102, which is connected to a drive signal receiving terminal. The drive circuit 103 is configured to generate a first drive control signal and a second drive control signal according to the control command of the control unit 60, and to provide the first drive control signal and the second drive control signal to the inverter circuit 70 and the switching circuit 90 respectively through the drive signal receiving terminal.

[0049] It should be noted that if limited by factors such as module packaging size and pin number, multiple switching tubes cannot be arranged in the integrated power module 101 to control the PTC heater 300, and only one switching tube can be used to control the PTC heater 300, and the heating position of the PTC heater 300 is adjusted by changing the duty cycle of the switching tube. The switching tube needs to be selected in a large current specification and a large size to ensure its heat dissipation reliability.

[0057] It should be noted that the first pin NC, the second pin NC, the ninth pin NC, the tenth pin NC, the eighteenth pin NC, the nineteenth pin NC and the twentieth pin NC of the integrated power module 101 are empty pins or pins used for other functions. The thirteenth pin NA of the integrated power module 101 is a useless pin.

[0058] In some embodiments, as shown in Figure 6 and Figure 8 As shown, the board body is further provided with a high-voltage positive power supply end, a high-voltage negative power supply end and a control output end, the high-voltage positive power supply end is connected with the positive direct current bus of the inverter circuit 70, the high-voltage negative power supply end is connected with the negative direct current bus of the inverter circuit 70, and the control output end is connected with the compressor motor 210 and the inverter circuit 70 respectively.
