Abstract
PURPOSE:To produce substantially constant high frequency output of an induction heating cooking oven even if the material of a pot is altered by controlling the conduction pulse of a switching element in response to the output obtained upon detection of the voltage of the switching element. CONSTITUTION:When a switching element 32 is turned off, the voltage of the voltage suppressing terminal C of the element 32 becomes sine waveform upon flowing of resonant current iC via a heating coil 31 and a resonant capacitor 34. When the voltage VCE alters from positive to negative, a diode 33 is conducted to flow a current iD to thereby flow a current determined by the impedance of the coil 31 through the element 32 before the current iD become zero. The current iF flowing through the element 32 is varied according to the material of a pot at the peak value of the current iF flowing through the element 32. When the peak suppressing voltage of the element 32 is set constant, the peak current also becomes constant to thereby produce constant induction heating output.
