Abstract
The present disclosure provides a method for controlling a power of an electromagnetic cooking appliance and an electromagnetic cooking appliance. The electromagnetic cooking appliance includes a first coil disk and a second coil disk. Each of the first coil disk and the second coil disk corresponds to an independent resonance circuit. After obtaining a target power of the electromagnetic cooking appliance, a heating period of the electromagnetic cooking appliance is determined based on the target power, each heating period including at least one first heating time period and at least one second heating time period. The first coil disk is controlled to heat in the first heating time period, and the second coil disk to heat in the second heating time period, such that the first coil disk and the second coil disk are heated alternately to reduce an interference of harmonic current and voltage flicker.
