Abstract

The invention discloses an electromagnetic heating control method. The method comprises the following steps of collecting a voltage of a collecting electrode in IGBT to generate a collection voltage; carrying out differential processing on the collection voltage; comparing the collection voltage after the differential processing to a preset voltage to generate an open signal; and according to the open signal, controlling IGBT conduction. In the invention, the voltage of the collecting electrode in the IGBT only needs to be detected so that the IGBT is controlled to be opened at the lowest point of resonance; a mode of comparing two voltages in the correlation technology is replaced and open losses of the IGBT are effectively reduced. The invention also discloses an electromagnetic heating control apparatus and an electromagnetic heating apparatus comprising the electromagnetic heating control apparatus.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electromagnetic heating control method, an electromagnetic heating control device and an electromagnetic heating device. Background technique [0002] In the induction cooker heating system, the coupling parameters of different pots and coil disks vary greatly, resulting in different synchronization states during the resonance process. In the related art, different cooking utensils and coil disks with different solid lines are in the same synchronous state during the resonance process, and the IGBT turn-on control uses the comparison of voltage divisions at both ends of the resonant coil to control the turn-on of the IGBT. However, it is difficult for related technologies to realize that the IGBT is turned on at the lowest point of resonance. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art ...
