Claim 9:
10. A system that includes an induction heat cooking apparatus and a secondary-side object, the induction heat cooking apparatus comprising:
a rectifier that is configured to convert AC voltage supplied from an external power source into 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;
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 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,
wherein, the mode conversion switch is configured to be opened in a cooking device heating mode and closed in a wireless power transfer mode,
wherein, based on coupling between the first capacitive unit and the second capacitive unit, the secondary-side object receives heat or receives wireless power from the induction heat cooking apparatus.
