Abstract: The present disclosure relates to an induction heating apparatus and a method of controlling the same. A controller of the induction heating apparatus according to the present disclosure may set an operation mode of an inverter circuit to a half bridge mode when a required power value of a working coil is set to a value less than a reference power value such that a driving frequency of the working coil decreases while an actual power value of the working coil is kept the same as the required power value. Additionally, the controller of the induction heating apparatus may adjust a duty ratio of a switching signal input to a switching element included in the inverter circuit, thereby adjusting the actual power value of the working coil.
