Filed: 1990-01-09
Abstract: PURPOSE:To vary heating power by changing resonance frequency of a resonance circuit formed out of a heating coil, resonance capacity, and of a magnetic amplifier. CONSTITUTION:Switching devices 8 and 9 are turned 'ON' by a control circuit 13, and a rectangular wave voltage having the same voltage amplitude as a dc power source 7 is applied to a resonance circuit formed out of a heating coil 10, resonance capacity 11, and of a magnetic amplifier 12, and sinusoidal current runs thereby.
