Patent ID: 8357883

Claim:
An induction heating system for inductively heating a target component mounted to a motor-driven vehicle, comprising: a polyphase-type alternating current motor adapted to drive the vehicle; an electrical storage device which stores an electric power to be supplied to the alternating current motor; an DC-AC converter adapted to convert a direct current from the electrical storage device into an alternating current, and supply the alternating current to the alternating current motor; and an induction heating coil adapted to receive a supply of the alternating current from the DC-AC converter, to inductively heat the target component, said DC-AC converter having: a positive terminal; a negative terminal; a plurality of first lines connected in parallel between said positive terminal and said negative terminal; two switching elements inserted in series in each of said plural first lines; said induction heating coil inserted between said two switching elements in series along said each of said plural first lines such that said two switching elements has a relationship which causes no supply of alternating current from the DC-AC converter to the alternate current motor even if said two switching elements are simultaneously turned on; wherein said polyphase-type alternating current motor has a plurality of electromagnetic coils each of which is electrically connected to respective one of said induction heating coil via a respective one of plurality of second lines.
