摘要

The present invention relates to a parallel resonant soft switching induction cooker having multiple loads for driving a plurality of loads in one inverter through a time division control and controlling a plurality of inverters in one control circuit. .;To this end, the present invention provides a voltage branching means comprising first and second filter capacitors Cf1 and Cf2 for branching an input voltage and improving a power factor, a plurality of resonant capacitors Cr1 to Crn, and a plurality of induction heating coils. A heating means consisting of a plurality of heating parts 200a to 200n for forming a resonant circuit (Lr1 to Lrn) to resonate an input voltage branched through the voltage branching means to selectively heat a plurality of heating plates (not shown); And a plurality of damping diodes D1 to D2n are reversely paralleled to the plurality of switches S1 to S2n switched according to a control signal input from the outside, and configured as switching means for selectively heating the heating means according to a switching action. do.
