摘要:
The present invention provides an induction heating apparatus that can detect that a power factor correction circuit is in operation or in non-operation. The induction heating apparatus includes a power factor correction circuit that corrects a power factor of an inputted direct-current power supply by turning on and off a switching element connected to a choke coil, a booster circuit that boosts an output voltage of the power factor correction circuit by turning on and off a switching element connected to a choke coil, an inverter circuit that inputs the output voltage of the booster circuit to generate a high-frequency current in a heating coil by turning on and off a switching element, and an inverter circuit drive control unit that, in driving the power factor correction circuit, controls output of the inverter circuit such that an input current reaches a target value and detects the voltage in the booster circuit. The inverter circuit drive control unit stops the output of the inverter circuit when it is detected that the power factor correction circuit is in non-operation.
