Abstract
Charging system and method using a motor driving system are proposed. The charging system includes a battery, an inverter to which D.C. power stored in the battery is applied, including a plurality of legs each including two switching elements, a motor including a plurality of coils of which first ends are respectively connected to connection nodes of the switching elements of each of the plurality of legs, and second ends are connected to each other to form a neutral point, and an inverter driving part configured to control switching of the switching elements, so that switching speeds of the switching elements are different for each mode of a motor driving mode and a charging mode so as to change magnitude of charging voltage supplied to the neutral point of the motor and to output the charging voltage to the battery.
