Claim 0:
1. An energy conversion system, comprising:
a bridge arm conversion module comprising a first bridge arm switch and a plurality of second bridge arm switches connected in parallel, wherein a bridge arm midpoint of the first bridge arm switch is configured to connect one of a live wire or a neutral wire of an alternating current charging interface, a bridge arm midpoints of each second bridge arm switch of the plurality of second bridge arm switches is configured to respectively connect to the other one of the live wire or the neutral wire of the alternating current charging interface via three phases of winding of a motor;
a bus capacitor connected parallel with the first bridge arm switch and the plurality of second bridge arm switches;
a direct current to direct current (DC/DC) conversion module configured to convert a bus voltage of the bus capacitor to charge a battery or convert the battery voltage to form the bus voltage;
wherein the bridge arm conversion module is configured to convert an alternating current input voltage supplied by the alternating current charging interface to form the bus voltage of the bus capacitor or drive the motor based on the bus voltage of the bus capacitor.
