Abstract
A control is performed so that phase angles of outputs from resonant inverters fall within a predetermined range under a mutual induction environment. An inductive heating device () includes: a plurality of resonant inverters () that supply power to a plurality of inductive heating coils (La, Lb), respectively, under a mutual induction environment; and a control circuit () that aligns drive frequencies so as to be in common among the resonant inverters and controls the drive frequencies commonly so that phase angles of the outputs from the plurality of the resonant inverters fall within a predetermined range. In addition, the control circuit individually controls coil currents flowing through the inductive heating coils so that the phase angles fall within a predetermined range.
