Abstract: PURPOSE:To reduce loss of an induction heating apparatus by altenatively switching switching elements which are respectively connected across both terminals of an auto-transformer, the midpoint of whose windings being connected to a terminal of a power source, and the other terminal thereof to restrict a transistor current in about half. CONSTITUTION:An induction heating apparatus consists of a d.c. power source 21, an auto-transformer 25, the midpoint C of whose windings being connected to a terminal of the d.c. power source 21, a load circuit 32 connected to both terminals of the auto-transformer 25 and a controller 35 for altenatively switching switching elements 26 and 29 respectively connected across the both terminals of the auto-transformer 25 and the other terminal of the d.c. power source 21. When the switching elements 26 and 29 are altenatively switched, the d.c. power source 21 applies heating power, altenatively through the switching elements 26 and 29, since the terminal of the d.c. power source 21 is connected to the midpoint C of the auto-transformer 25. The currents of the switching elements 26 and 29 are thus restricted in about half compared to the conventional apparatus. Therefore, the switching elements 26 and 29 require less capacity to minimize heating to be loss.
