In order to improve the lower power factor ,output voltage fluctuation and other defects of the existing DC600 V power supply, the design of the main circuit based on＇the rectifier Diode＋IGBT buck chopper＇ is designed in this paper. By PSIM software,the work cases of different input voltage of the main circuit is simulated. The results show that it makes the output voltage stahillized between 600 V in 10ms,and greatly increase the Power Factor, reach the expected goal.So the new Passenger Car＇s DC600 V Power Supply meets the demand of Passenger car and ensure the normal operation of the electric equipment.
