Abstract

An induction heating method comprising the steps of supplying a plurality of heating coils with electricity by resonance-type inverters respectively corresponding to said heating coils with one of said resonance-type inverters being a main inverter and another being a subordinate inverter, driving said subordinate inverter in such a manner that a phase of a current supplied to said heating coil on a subordinate side is synchronized with a phase of a current supplied to said heating coil on said main side or maintained at a phase difference to be set, based on a drive signal of said main inverter or an output voltage or an output current of said main inverter.
