Title:
INDUCTION HEATING DEVICE
Document Type and Number:
Japanese Patent JP3456209
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To devise a reduction of loss and miniaturization of a cooling device or the like by reducing the number of diodes through which, a heating coil operating current flows.
SOLUTION: A diode serial circuit composed of two diodes 2, 3, a capacitor serial circuit composed of two capacitors 4, 5, and a switching arm serial circuit, composed of two switching arms of which one is composed of a switching element 6 and a diode connected in antiparallel, and the other is composed of a switching element 7 and a diode 9 connected in antiparallel, are connected in parallel. One end of an alternating current power source 1 is connected to the inside connection point of the diode serial circuit, and the other end of an alternating current power source 1 is connected to the inside connection point of the capacitor serial circuit. Further, one end of the parallel circuit of a heating coil 11 and a capacitor 10 is connected to the inside connection point of the switching arm serial circuit, and the other end is connected to the inside connection point of the capacitor serial circuit.
