Abstract

The invention discloses an electromagnetic heating appliance and a control method and device of the electromagnetic heating appliance. The method comprises the steps of obtaining a first temperature of a first power tube and a second temperature of a second power tube, and according to the first temperature and the second temperature, adjusting the ratio of the high level to the low level of the output pulse width modulation signal so as to reduce the turn-on time of the power tube with the higher temperature in the first power tube and the second power tube. According to the control method of the electromagnetic heating appliance provided by the embodiment of the invention, the temperature rise problem of the power tube is effectively solved, and the service life of the power tube is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an electromagnetic heating appliance and a control method and device for the electromagnetic heating appliance. Background technique [0002] In an induction cooker with a half-bridge topology, two power tubes (Insulated Gate Bipolar Transistor, IGBT for short) are used to control and generate an alternating magnetic field. The temperature of the IGBT prevents the IGBT from overheating and burning when it is abnormal [0003] In related technologies, two sets of temperature measuring circuits are generally used to detect the temperature of the IGBT. Due to the high power, the current flowing through the IGBT is relatively large, and the IGBT is generally fixed on the heat sink and dissipated by a cooling fan. [0004] However, in the actual process, due to the different fixed positions of the IGBTs, the heat dissipation effects are different, resulting in inconsis...
