WPT PFC INDUCTION HEAT COOKING APPARATUS TO IMPLEMENT WPT AND PFC POWER CONVERTER

摘要

According to an embodiment of the present invention, an electronic induction heating cooker comprises a rectifying unit for converting an AC voltage supplied from an external power source into a DC voltage; an inverter for supplying current to a heating coil using voltage output from the rectifying unit; a heating coil for generating a magnetic field when the current flows by the inverter; a resonant capacitor including a plurality of capacitors connected in series between the heating coil and both ends of DC having voltage output from the rectifying unit; a WPT capacitor which can be connected to the resonant capacitor in parallel; and a mode conversion switch for determining whether to connect the resonant capacitor and the WPT capacitor in parallel.
