摘要： PURPOSE:To control constant the power supplied to a high frequency induction heating coil, accordingly the power consumed by objects to be heated having different impedances such as beverage cans, when they are heated by such a heating coil, without changing the supply voltage of high frequency power supply to be supplied to a resonance circuit. CONSTITUTION:Objects to be heated (for example, beverage cans) 13 and a high frequency induction heating coil 5 are located opposingly, and from a high frequency power supply (for example, high frequency power supply part 2), a high frequency current is fed to a resonance circuit 3 which includes said heating coil 5 as a component element, and thereby the objects 13 are subjected to high frequency induction heating. When the high frequency current flowing in the coil 5 has attained the set amperage, it is shut off, followed by again feeding the high frequency current, in repetitions to constitutes a shut-off control. Thereby the high frequency power supplied to the coil 5 is made constant substantially.
