Claim 0:
1. A charging system using a motor driving system, the charging system comprising:
a battery;
an inverter to which D.C. power stored in the battery is applied, the inverter comprising a plurality of legs each comprising two switching elements connected to each other in series;
a motor comprising a plurality of coils of which first ends are respectively connected to connection nodes of the switching elements included in 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 to provide different switching speeds of the switching elements for a motor driving mode operated for controlling the switching elements in the inverter for driving the motor and a charging mode operated for controlling the switching elements in the inverter 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,
wherein the inverter driving part is configured to determine that the switching speeds of the switching elements in the charging mode are slower than the switching speeds of the switching elements in the motor driving mode.
