Abstract
The present disclosure provides a motor drive integrated on-board charger to reduce the quantity of components in an electric system of an electric vehicle. Reduction of components is achieved by utilizing the motor and the motor driving inverter as a part of the on-board charger in the charging mode. By controlling relays, electrical connections of the system may be reconfigured according to its mode of operation. In one aspect, the motor and the motor driving inverter play the roles of a boost PFC, a current regulator, or both.
