Claim 1:
2. An energy conversion apparatus comprising: a three-phase bridge arm converter, a motor winding, and a transformer, wherein
a direct current port of the three-phase bridge arm converter is connected to a battery;
an alternating current port of the three-phase bridge arm converter is connected to the motor winding;
two bridge arms of the three-phase bridge arm converter are connected to a secondary-side winding of the transformer through a first switch group, and the first switch group is configured to control connection and disconnection between the transformer and the two bridge arms of the three-phase bridge arm converter;
a second switch group is further disposed between the motor winding and the two bridge arms of the three-phase bridge arm converter, and the second switch group is configured to control connection and disconnection between the motor winding and the two bridge arms of the three-phase bridge arm converter; and
a primary-side winding of the transformer is connected to an alternating current charging port.
