Abstract
PURPOSE:To secure the steady operation for the device used in the inductive heating cooker or the like regardless of fluctuation of the power voltage, the load and others by giving the feedback control to the input current or the power switching semiconductor voltage. CONSTITUTION:Inverter circuit 3, which supplies the DC power obtained by rectifying the low-frequency AC through rectifier circuit 2, consists of resonance inductor 31 doubling the inductive heating coil, resonance capacitor 34, power switching semiconductor 32 and others, and is controlled by control circuit 4. For circuit 4, output voltage vi and vc of input current detection circuit 46 detecting the input current supplied to circuit 3 via current fransformer 40 and terminal voltage detection circuit 47 detecting the terminal voltage of semiconductor 32 are supplied to comparator circuit 50 to which saw-tooth wave signal vr sent from ramp generator 51 via OR circuit 49. Then the output whose pulse duration is controlled in accordance with the higher level between signals vi and vc is applied to semiconductor 32 via drive circuit 53 to control the conducting period.
