An induction heating apparatus according to one embodiment may confirm a feature of a container and determine an operation mode based on the feature of the container before performing an operation of heating the container. In one embodiment, the operation mode of the induction heating apparatus may be determined as any one of a frequency doubler mode, a half bridge mode, and a full bridge mode. In one embodiment, a power control mode of the induction heating apparatus may be determined based on an operation mode of the induction heating apparatus. In one embodiment, the power control mode of the induction heating apparatus may be determined as any one of an asymmetric pulse width modulation (APWM) mode and a phase shift mode.

Induction heating apparatus and method for controlling same

The present invention relates to an induction heating cooker including a synchronization circuit for a plurality of inverters, comprising: a first inverter including a first switching circuit unit for applying a first power source to a first heating coil, and a first control unit for controlling the first switching circuit unit; and a second inverter including a second switching circuit unit for applying a second power source to a second heating coil, and a second control unit for controlling the second switching circuit unit, wherein the first inverter further includes a first insulated signal transfer unit for controlling an operation of the second switching circuit unit, and the first control unit may match an operating frequency of the second switching circuit unit with an operating frequency of the first switching circuit unit by using the first insulated signal transfer unit.
