PCT No. PCT/JP82/00426 Sec. 371 Date Jul. 5, 1983 Sec. 102(e) Date Jul. 5, 1983 PCT Filed Nov. 2, 1982 PCT Pub. No. WO83/01721 PCT Pub. Date May 11, 1983.An induction heating device makes use of a bridge inverter and has a DC power source, a plurality of switching elements forming a bridge inverter, and a circuit for detecting the turn-off of the switching elements. In order to detect the turn-off of the switching elements, an improved turn-off detection circuit is employed and an improved control circuit is installed to prevent the circuit from malfunctioning owing to external noise.
