Abstract:
An induction heating apparatus is provided. The induction heating apparatus includes a heating coil, an inverter, a current sensor configured to measure a driving current supplied from the inverter to the heating coil, and a controller configured to provide a drive signal to the inverter to allow the driving current to follow a target current based on a user input. The controller reduces a driving duty of the drive signal based on the driving current exceeding a predetermined reference current, and the controller provides a drive signal to the inverter to allow the driving current to follow a current less than the target current, based on the driving current being less than or equal to the predetermined reference current after reducing the driving duty of the drive signal.
