Abstract
The present invention includes: a plurality of induction heating coils () which are disposed adjacently; capacitors () each of which is connected in series thereto; a plurality of inverters () each of which applies a high frequency voltage converted from a DC voltage to each series resonant circuit of the induction heating coil and the capacitor; and a control circuit () which operates the plurality of the inverters with a same frequency and current synchronization, controls so that a phase difference becomes minimal at a specific inverter, which supplies the maximum power to the plurality of the induction heating coils, between the high frequency voltage generated therefrom, and a resonant current flowing the series resonant circuit, and set a DC power supply voltage Vdc applied to the plurality of the inverters so that the output voltages (Vinv) become greater than mutual induction voltages (Vm).
