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. The method for controlling the power includes the following steps: obtaining a target power of the electromagnetic cooking appliance; determining a heating period of the electromagnetic cooking appliance based on the target power, in which, each heating period includes at least one first heating time period and at least one second heating time period; controlling the first coil disk to heat in the first heating time period, and controlling the second coil disk to heat in the second heating time period, in which, each first heating time period is followed by the second heating time period to make the first coil disk and the second coil disk heat alternately. The method may realize to switch heating in high speed on a plurality of coil disks, to heat with different powers, and further to reduce an interference of harmonic current and voltage flicker.
