Abstract

This invention relates to an induction heating device and a control method for the induction heating device. One embodiment of the induction heating device determines its operating mode based on the characteristics of the container. In one embodiment, the operating mode of the induction heating device can be determined as any one of a frequency doubler mode, a half-bridge mode, or a full-bridge mode. Furthermore, in one embodiment, the power control mode of the induction heating device can be determined as any one of an asymmetric pulse width modulation (APWM) mode and a phase shift mode.
