INDUCTION HEATING APPARATUS

摘要

An induction heating apparatus capable of stop heating without excessively boosting output voltages of a booster circuit and a power factor correction circuit is provided. The induction heating apparatus includes a boosting function unit, an inverter circuit 15 and a booster circuit controller 32. The boosting function unit which includes a power factor correction circuit 7 and a booster circuit 14, inputs a direct-current power, boosts the input direct-current power to a direct-current voltage having a peak value larger than the peak value of the input direct-current power by turning on/off a switching element, and outputs the boosted voltage. The inverter circuit 15 which includes a heating coil 21, inputs the direct-current voltage output by the boosting function unit to generate a high frequency current in the heating coil 21 by turning on/off operation of a different switching element. The booster circuit controller 32 stops a boosting operation of the boosting function unit without a prescribed delay or more from the stop of an operation of the inverter circuit 15.
