Abstract

The present invention relates to a device for suppressing electromagnetic coupling, a control circuit, and an electric appliance and a control method thereof. The device includes at least two branches; each of the branches includes a resonant circuit and a power drive module, wherein the power drive module is connected to the resonant circuit; and at least one of the branches further includes a switch module, and the switch module is disposed on the resonant circuit of the branch. The device can flexibly suppress the electromagnetic coupling between the resonant circuits, and solve the problemof increasing the failure risk of the power driving modules due to the superposition of the electromagnetic coupling energy.

Description

technical field [0001] The invention belongs to the field of electrical appliances, and in particular relates to a device for suppressing electromagnetic coupling, a control circuit, an electrical appliance and a control method thereof. Background technique [0002] With the development of science and technology, people need more and more household appliances in their daily life. Many household appliances use electromagnetic heating. The following methods are usually used: a single power drive module controls multiple independent resonant circuits, Or a plurality of independent resonant circuits are respectively controlled by a plurality of power drive modules, wherein the resonant circuit is a module used to provide heating, which can achieve centralized heating of the bottom, side wall or top of the pot and other local positions, and the The heating control required for rice performance brings greater flexibility, and its control is precise, even heating, and higher effici...
