Description
technical field [0001] The invention relates to the field of electrical appliances, in particular to a heating control circuit for an electromagnetic cooking appliance and the electromagnetic cooking appliance. Background technique [0002] The induction cooker mainly uses high-power switching devices (such as IGBT (Insulated Gate Bipolar Transistor, Insulated Gate Bipolar Transistor), etc.) to drive the coil plate to generate an alternating magnetic field to heat up the pot in it to achieve the purpose of heating. [0003] In the related art, one or two switching devices are used to control a coil disk for heating in the heating circuit. The inventors of the present application have found that this control method does not affect the hardware in the circuit (for example, resonant capacitors, coil disks, switching devices, etc.) etc.) to maximize utilization. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a heating ...
