[0002] The traditional inverter power supply for pure electric vehicles adopts the design of industrial-grade inverter power supply, and its power module adopts the design of industrial-grade devices, which greatly reduces the stability and reliability of the vehicle-mounted inverter; and the traditional vehicle-mounted inverter power supply The DC-DC boost circuit is adopted, and the system input and output are not electrically isolated, which poses a greater safety hazard

At the same time, the power design of the traditional vehicle-mounted inverter power supply is relatively small, and the heat dissipation method is fan-cooled, the continuous working time is short, and the system IP level (the protection level of the electrical equipment shell against the intrusion of foreign objects) is relatively low, which can no longer meet the needs of electric vehicles. High power, high stability and high reliability requirements for automotive inverter systems
