摘要： A power conversion system for vehicles is provided. The system includes a switching circuit having first input/output terminals, second input/output terminals and a plurality of switching elements connected between the first input/output terminals and the second input/output terminals. A first energy storage device is connected to the second input/output terminals and has a preset charging/discharging voltage. A first voltage conversion circuit converts power output from the first input/output terminals to output a voltage less than the voltage of the first energy storage device. A second energy storage device is charged/discharged with the output voltage of the first voltage conversion circuit. A controller controls open/short-circuit states of the switching elements based on whether the first energy storage device is being charged and whether the vehicle is traveling. When the first energy storage device is being charged, AC charging power is provided to the first input/output terminals from outside of the vehicle.
