ELECTRIC MOTOR DRIVING SYSTEM AND VEHICLE

This application relates to the field of vehicle control technologies, and provides a motor-driven system and a vehicle, to simplify a structure of the motor-driven system and reduce costs. The motor-driven system includes: a bidirectional charger, an excitation drive component, and a motor controller. The bidirectional charger includes: a power factor correction circuit, a first voltage conversion circuit, a first transformer, and a second voltage conversion circuit. An electricity storage unit is electrically connected to a second terminal of the second voltage conversion circuit. The excitation drive component is electrically connected to a multiplexing node by using a first switch unit, the multiplexing node is located between the power factor correction circuit and the first voltage conversion circuit, and the excitation drive component is configured to drive an excitation generator.
