Classification: CPC H  F  Y | IPC F  H

Claim 0:
1. An induction heat cooking apparatus comprising:
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, and
wherein the mode conversion switch is configured to be opened in a cooking device heating mode and closed in a wireless power transfer mode.
