PROBLEM TO BE SOLVED: To provide a power circuit for an induction heating cooker which does not need to be cooled by a cooling fan. SOLUTION: A power supply circuit which supplies a high frequency current to the induction heating coil of an induction heating cooker is provided with first and second electric circuits 32A, 32B in which one end 25a of the induction heating coil 25 is connected to an ac power supply 30 and the other end 25b of the induction heating coil 25 is connected to the ac power supply 30. Switching elements 33A, 33B driven by a drive circuit 37 and capacitors 35A, 35B are inserted in the first and second electric circuits 32A, 32B. Bypass electric circuits 32A, 32B are provided bypassing the switching elements 33A, 33B of the first and second electric circuits and having rectifying elements 41A, 41B inserted therein for connecting the other end 25b of the induction heating coil 25 to the capacitors 35A, 35B. |
