Abstract:
An induction heating apparatus may include a first working coil provided in a position corresponding to a first heating region, a second working coil provided in a position corresponding to a second heating region, an inverter circuit configured to supply current for driving at least one of the first working coil or the second working coil, and a drive circuit configured to supply a switching signal to each of the switching elements. A controller may be configured to determine a driving mode of the working coil when a heating start command for at least one of the first working coil or the second working coil is input, and the controller may provide a control signal for outputting the switching signals based on the determined driving mode.
