Abstract:
An induction heat cooking apparatus that includes: a rectifier that is configured to convert alternating current (AC) voltage supplied from an external power source into direct current (DC) voltage; an inverter that is configured to generate current based on DC voltage received from the rectifier and provide the current to output nodes; heating coils that are configured to, based on the current generated by the inverter, generate magnetic fields for providing heat; a first capacitive unit that includes one or more resonance capacitors and that is coupled between the output nodes; a second capacitive unit that includes one or more wireless power transfer (WPT) capacitors and that is configured to be coupled between the output nodes; and a mode conversion switch that is configured to couple the second capacitive unit to the first capacitive unit in parallel is disclosed.
