[0034] Existing controllers need to convert high-voltage electrical signals into low-voltage electrical signals. Due to the structural and assembly limitations of the controller cover itself, the electromagnetic compatibility (EMC) of the controller is insufficient and may have loopholes, resulting in poor EMC performance of the controller.
[0035] To solve the above technical problems, refer to Figures 1 to 5As shown, this application provides a controller, including a housing 10, a capacitor 20, an IGBT module 30, a filter assembly 40, and an isolation plate 50. The housing 10 forms a first receiving slot 11, a second receiving slot 12, and a third receiving slot 13, with the second receiving slot 12 located between the first receiving slot 11 and the third receiving slot 13. The capacitor 20 is disposed in the first receiving slot 11. The IGBT module 30 is disposed on the capacitor 20 and is electrically connected to the capacitor 20. The circuit board 31 of the IGBT module 30 extends into the second receiving slot 12. The circuit board 31 has a low-voltage control section 311 located outside the second receiving groove 12; the filter assembly 40 includes a high-voltage copper busbar 41, which includes a copper busbar body 411 and a high-voltage terminal 412. The copper busbar body 411 is located in the third receiving groove 13, and the high-voltage terminal 412 is located in the second receiving groove 12 and electrically connected to the capacitor 20; the isolation plate 50 includes a first isolation section 51, which is located at the opening of the second receiving groove 12 to isolate the low-voltage control section 311 of the circuit board 31 from the high-voltage terminal 412. Therefore, the first receiving slot 11 of the housing 10 accommodates the capacitor 20 and part of the IGBT module 30, the second receiving slot 12 accommodates the high voltage terminal 412 of the high voltage copper busbar 41 and places part of the circuit board 31 at the corresponding position of the second receiving slot 12, and the third receiving slot 13 accommodates the copper busbar body 411 of the high voltage copper busbar 41. The capacitor 20 and the high voltage terminal 412 are placed in the second receiving slot 12. Since the circuit board 31 is also located outside the second receiving slot 12, and the low voltage control part 311 of the circuit board 31 has a low voltage electrical signal and the high voltage terminal 412 has a high voltage electrical signal, a first isolation part 51 needs to be set at the slot opening of the third receiving slot 13 to isolate the low voltage electrical signal of the low voltage control part 311 and the high voltage electrical signal of the high voltage terminal 412, so as to reduce the electromagnetic interference of the low voltage electrical signal and the high voltage electrical signal, thereby improving the EMC performance of the controller.
[0036] In some embodiments, refer to Figure 1 and Figure 2 As shown, the controller also includes a top cover 80, which is connected to the housing 10. The top cover 80 and the housing 10 cooperate to form a receiving cavity 81, in which the capacitor 20, IGBT module 30, filter assembly 40, and isolation plate 50 are disposed. The shape of the top cover 80 corresponds to that of the housing 10 to seal the top cover 80 and the housing 10. The receiving cavity 81 formed between the top cover 80 and the housing 10 includes a first receiving groove 11, a second receiving groove 12, and a third receiving groove 13. The capacitor 20, IGBT module 30, filter assembly 40, and isolation plate 50 are correspondingly disposed in the first receiving groove 11, the second receiving groove 12, and the third receiving groove 13 of the receiving cavity 81, and are then sealed by the top cover 80, thereby isolating the internal components from the external components.
[0037] In some embodiments, the first receiving slot 11 is set according to the size of the capacitor 20 and the IGBT module 30, the third receiving slot 13 is set according to the size of the filter component 40, the third receiving slot 13 is set according to the size of the high voltage terminal 412, and the circuit board 31 extends to the outside of the slot opening of the third receiving slot 13, which can partially cover the slot opening of the third receiving slot 13 or completely cover the slot opening of the third receiving slot 13.
[0038] In some embodiments, the high-voltage copper busbar 41 of the filter assembly 40 is used to receive the DC power from the battery, and converts the DC power into AC power and low-voltage power in sequence through the capacitor 20 and the IGBT module 30. The AC power is used to drive the motor or compressor to rotate, and the low-voltage power is used to control the compressor.
[0039] In some embodiments, the low-voltage control unit 311 may include a chip, integrated circuit, etc., for implementing control and control calculation of the drive motor or compressor. The low-voltage control unit 311 is disposed on the portion of the circuit board 31 extending into the second receiving groove 12, thereby being able to be away from the high-voltage portion of the IGBT module 30.
[0040] In some embodiments, refer to Figure 1 and Figure 3 As shown, the isolation plate 50 is a metal plate, and the size of the isolation plate 50 corresponds to the size of the opening of the second receiving groove 12, so as to isolate the low-voltage control unit 311 and the high-voltage terminal 412 as much as possible, thereby reducing the interference between the low-voltage electrical signal of the low-voltage control unit 311 and the high-voltage electrical signal of the high-voltage terminal 412.
[0041] In some embodiments, refer to Figures 3 to 5 As shown, the housing 10 forms a mounting portion 14, which is located between the first receiving groove 11 and the third receiving groove 13. The mounting portion 14 is adjacent to the second receiving groove 12, and the circuit board 31 extends beyond both the second receiving groove 12 and the mounting portion 14. Along the length of the controller, the first receiving groove 11, the second receiving groove 12, and the third receiving groove 13 are arranged sequentially; along the width of the controller, the second receiving groove 12 and the mounting portion 14 are arranged sequentially. The IGBT module 30 is partially located in the first receiving groove 11, partially in the second receiving groove 12, and partially in the mounting portion 14. A portion of the IGBT module 30 in the first receiving groove 11 is located on the capacitor 20. This design allows for a more compact layout of the IGBT module 30.
[0042] In some embodiments, refer to Figures 3 to 5As shown, a first isolation rib 61 is formed between the mounting portion 14 and the third receiving groove 13, and a second isolation rib 62 is formed between the second receiving groove 12 and the third receiving groove 13. An opening 63 is formed between the first isolation rib 61 and the second isolation rib 62. The isolation plate 50 includes a second isolation portion 52, which is set at an angle to the first isolation portion 51 and is located at the opening 63. The first isolation rib 61 can isolate the mounting portion 14 and the third receiving groove 13, and the second isolation rib 62 can partially isolate the second receiving groove 12 and the third receiving groove 13, thereby reducing electrical signal interference between the mounting portion 14 and the third receiving groove 13, and between the second receiving groove 12 and the third receiving groove 13. Since the copper busbar body 411 and the high-voltage terminal 412 are integrated, the opening 63 formed between the first isolation rib 61 and the second isolation rib 62 facilitates the installation of the high-voltage copper busbar 41. After the high-voltage terminal 412 and the copper busbar body 411 are installed, an isolation plate 50 is installed outside the slot of the second receiving groove 12. The first isolation part 51 of the isolation plate 50 is located at the slot of the second receiving groove 12, and the second isolation part 52 of the isolation plate 50 is located at the opening 63, thereby isolating the low-voltage control part 311 and the third receiving cavity 81 and reducing electrical signal interference.
[0043] In some embodiments, refer to Figures 3 to 5 As shown, the included angle between the first isolation section 51 and the second isolation section 52 is approximately 90 degrees, forming an "L" shape, which can simultaneously isolate the slot and opening 63 of the second receiving groove 12, increasing the isolation effect. Correspondingly, an isolation structure corresponding to the isolation plate 50 is provided on the housing 10, thereby isolating the low-voltage control section 311 of the IGBT module 30 from the high-voltage area of the IGBT module 30.
[0044] In some embodiments, refer to Figures 4 to 7 As shown, the circuit board 31 includes a control terminal 312; the mounting portion 14 forms a first isolation groove 141; the controller also includes an isolation cover 70 disposed on the side of the circuit board 31 facing away from the mounting portion 14, the isolation cover 70 forming a second isolation groove 71, the side of the control terminal 312 facing the mounting portion 14 is located in the first isolation groove 141, and the side of the control terminal 312 facing away from the mounting portion 14 is located in the second isolation groove 71. The control terminal 312 is used for electrical connection with external low-voltage control lines and low-voltage control equipment. By placing the side of the circuit board 31 close to the mounting portion 14 in the first isolation groove 141 and the side of the circuit board 31 facing away from the mounting portion 14 in the isolation cover 70, the control terminal 312 can be isolated from high-voltage electrical signals, reducing electrical signal interference.
[0045] In some embodiments, refer to Figures 4 to 8As shown, the controller also includes an output copper busbar 90, which is connected to the IGBT module 30 and is located on the side away from the filter assembly 40. The output copper busbar 90 is used to output the AC power generated by the IGBT module 30 to an external drive motor or compressor. Since the output copper busbar 90 also has a high-voltage signal, its location on the side away from the filter assembly 40 can keep it away from the low-voltage control section 311 and control terminal 312 of the circuit board 31, thereby reducing electrical signal interference between them. At the same time, placing the output copper busbar 90 and the high-voltage copper busbar 41 on opposite sides of the IGBT module 30 makes the structure easier to arrange and simplifies assembly.
[0046] In some embodiments, refer to Figures 4 to 8 As shown, a third isolation rib 1411 is formed radially in the first isolation groove 141; the circuit board 31 includes a first copper plating area 313, and the control terminal 312 is located within the first copper plating area 313. The first copper plating area 313 is located on the side of the circuit board 31 facing the mounting portion 14. The first copper plating area 313 is connected to the third isolation rib 1411 to isolate the control terminal 312 on the side of the circuit board 31 facing the mounting portion 14. The shape of the third isolation rib 1411 corresponds to the shape of the first copper plating area 313 to enable the two to be installed together. The third isolation rib 1411 is made of metal to cooperate with the first copper plating area 313 to achieve a better isolation effect. The first copper plating area 313 and the third isolation rib 1411 are configured to surround the control terminal 312, and the specific configuration is selected according to the actual situation. The first copper-plated area 313 and the third isolation rib 1411 are connected by a locking device. This design can reduce the situation where the control terminal 312 is too long and cannot be fully placed in the first isolation groove 141. Furthermore, the combination of the first copper-plated area 313 and the metal third isolation rib 1411 provides better isolation for the control terminal 312.
[0047] In some embodiments, refer to Figures 4 to 9 As shown, the isolation cover 70 forms a second isolation groove 71; the circuit board 31 includes a second copper plating area 314, which is located on the side of the circuit board 31 opposite to the mounting portion 14, and is connected to the opening of the second isolation groove 71. The isolation cover 70 is a metal isolation cover, and locking holes are provided around the circumference of the isolation cover 70. The opening of the second isolation groove 71 corresponds to the shape of the second copper plating area 314, so that the two can be locked together through the locking holes. This design can reduce the situation where the control terminal 312 is too long to be fully placed in the second isolation groove 71, and the combination of the first copper plating area 313 and the metal isolation cover 70 provides a better isolation effect for the control terminal 312.
[0048] Reference Figures 4 to 9As shown, by providing a first isolation groove 141 on the side of the circuit board 31 facing the mounting part 14 and an isolation cover 70 on the side of the circuit board 31 away from the mounting part 14, both sides of the control terminal 312 can be isolated, thereby achieving a better isolation effect.
[0049] In some embodiments, refer to Figures 4 to 9 As shown, the first isolation groove 141 is provided with a hole 1412, through which the control terminal 312 passes to facilitate external connection.
[0050] In some embodiments, combined with Figure 3 and Figure 10 As shown, the filter assembly 40 also includes an amorphous magnetic ring 42, a first-order filter capacitor bank 43, a ferrite magnetic ring 44, and a second-order filter capacitor bank 45. These components are arranged on the copper busbar body 411 from the side furthest from the capacitor 20 to the side closest to it. The amorphous magnetic ring 42, the first-order filter capacitor bank 43, the ferrite magnetic ring 44, and the second-order filter capacitor 20 are located in the third receiving slot 13. The amorphous magnetic ring 42, the first-order filter capacitor bank 43, the second-order filter capacitor bank 45, and the ferrite magnetic ring 44 are used to eliminate interference from surrounding signals. In the circuit, they play multiple roles, including noise filtering, voltage stabilization, energy storage, and electromagnetic interference suppression. Their combined operation further reduces electromagnetic interference between the high-voltage copper busbar 41 and the outside world.
[0051] In this application, the first isolation rib 61 can isolate the mounting part 14 and the third receiving groove 13, and the second isolation rib 62 can partially isolate the second receiving groove 12 and the third receiving groove 13. By providing the first isolation part 51 at the opening of the third receiving groove 13 to isolate the low-voltage electrical signal of the low-voltage control part 311 and the high-voltage electrical signal of the high-voltage terminal 412, and the second isolation part 52 of the isolation plate 50 is located at the opening 63 between the first isolation rib 61 and the second isolation rib 62, the electrical signal interference between the mounting part 14 and the third receiving groove 13, and between the second receiving groove 12 and the third receiving groove 13 is reduced. This design can reduce the electromagnetic interference of low-voltage and high-voltage electrical signals, thereby improving the EMC performance of the controller.
