ENERGY CONVERSION APPARATUS, POWER SYSTEM, AND VEHICLE

Embodiments of this application provide an energy conversion apparatus, a power system, and a vehicle. The energy conversion apparatus includes a first switch group, a second switch group, a third switch group, a three-phase converter, a motor coil, a bridge arm circuit, and a three-port converter. The energy conversion apparatus is integrated with functions of alternating-current charging, motor driving, and direct-current charging, and can be installed on an electric vehicle to improve vehicle integration, thereby simplifying a structural layout of the electric vehicle, and reducing costs and a volume of the electric vehicle.
