Induction heater and method for controlling same

A method for controlling an induction heater comprising:

• rectifying, using a rectifier circuit, an alternating current input power, the rectifier circuit being connected to a power factor correction (PFC) circuit which is connected to a direct current (DC) link capacitor, the DC link capacitor being connected to an inverter circuit configured to apply a drive current to a heating coil,
• operating a first switching element of the PFC circuit and a second switching element of the PFC circuit to be complementary with each other, based on receiving a user input to turn on the induction heater, the first switching element and the second switching element being connected to a ground node,
• wherein the PFC circuit comprises:
• a first inductor configured to be connected to an output node of the rectifier circuit, the first inductor being connected to the first switching element;
• a second inductor connected to the output node of the rectifier circuit and connected in parallel with the first inductor, the second inductor being connected to the second switching element;
• a first diode connected to the first inductor and the DC link capacitor;
• a second diode connected to the second inductor and the DC link capacitor.
