The invention discloses a method for controlling the power of electromagnetic heating equipment and the electromagnetic heating equipment, the electromagnetic heating equipment is provided with an IGBT, and the method comprises the following steps: receiving a shutdown instruction; determining the current power of the electromagnetic heating equipment; judging whether the current power is greaterthan preset power or not; if so, reducing the current power, wherein the step of reducing the current power comprises the following sub-steps: acquiring a current current value of the electromagneticheating equipment; judging whether the current current value is greater than a preset current value or not; and if so, reducing the current current value so as to reduce the current power During shutdown, if the current power of the electromagnetic equipment is relatively high, the IGBT is easily damaged due to direct shutdown. At the moment, the shutdown program can be executed after the currentpower is reduced, so that the IGBT damage probability is reduced, the service life of the equipment is prolonged, and the user experience is improved.
Description
technical field [0001] The present application relates to the field of electromagnetic heating equipment, in particular to a method for controlling the power of electromagnetic heating equipment and the electromagnetic heating equipment. Background technique [0002] Electromagnetic heating equipment refers to equipment that heats through the principle of electromagnetic induction, such as induction cooker, electromagnetic induction heater, etc. An insulated gate bipolar transistor (Insulated Gate Bipolar Transistor, IGBT) is usually provided in an electromagnetic heating device, which plays an important role of a power switch to control heating. However, during the use of electromagnetic heating equipment, especially in the power start and stop stages, the IGBT is prone to burst tube damage. [0003] In the prior art, various manufacturers have strict controls and standards on the timing and turn-on width of the start-up power of the IGBT, so as to reduce the probability o...
