Abstract
The invention discloses a single-motor inverter assembly. The single-motor inverter assembly comprises a main box, an IGBT module, a driving board, a driving board heat dissipation gasket, a three-phase bus, a three-phase bus fixing bracket, a current sensor, a DC bus capacitor, a discharge resistance, a DC bus connection seat assembly, an upper box, a control board, a shielding cover, a flat cable, a high-voltage direct current connector and a high-voltage alternating current connector. The single-motor inverter assembly adopts a direct-current bus bar wiring seat assembly, so that the integrated level of the single-motor inverter is higher, and the structure is more compact; the parts such as the IGBT module, the capacitor, the DC bus bar connection seat assembly, the control board and the like are respectively arranged on the main box body and the upper box body according to a specific position, and the space is fully utilized, so that the volume is smaller and the power density ishigher; the capacitor, the direct current bus bar connection seat assembly, the direct current bus fixing bracket and the control board are positioned so that the assembly is more convenient; the control board is provided with the shielding cover, and the direct current input end is connected with a Y capacitor, so that the electromagnetic compatibility is better; the high-pressure air-conditioning connector and the fuse are integrated, and a structure for supplying power to the air-conditioning compressor is not needed, and the integration level is higher.
Description
technical field [0001] The invention belongs to the field of inverters, in particular to a single-motor inverter assembly. Background technique [0002] With environmental pollution and consumption of petroleum energy, the development of electric vehicles has become a consensus, especially after the introduction of stricter emission regulations, the development of electric vehicles is imminent. As a key component of electric vehicles, inverters have higher requirements. [0003] Many inverters in the prior art are characterized by large volume, low power density, low integration, poor safety, etc., and it is difficult to meet the increasingly stringent vehicle requirements and regulatory requirements. Contents of the invention [0004] In view of the shortcomings of the above existing technical solutions, the purpose of the present invention is to provide a single-motor inverter assembly with high power density, which can not only satisfy the convenience of vehicle layout...
