Problems solved by technology
[0004] Since both the induction cooker and the wireless power supply system have a resonant circuit for generating an alternating magnetic field, if the induction cooker and the wireless power supply system can share a resonant circuit, the production cost will be greatly reduced. However, no similar technology has been proposed in the related art Program

The invention provides a control method and system for an electromagnetic device and the electromagnetic device. The control method for the electromagnetic device comprises the steps of judging whether a heating signal or a wireless power supply signal is received; when it is determined that the heating signal is received, outputting an alternating magnetic field with first frequency to achieve electromagnetic heating; when it is determined that the wireless power supply signal is received, outputting an alternating magnetic field with second frequency to supply wireless energy to loads. The electromagnetic device can achieve corresponding functions, namely, the electromagnetic heating function and the wireless power supply function, according to different received signals, so that the production cost is lowered.
Description
Technical field [0001] The present invention relates to the technical field of electromagnetic induction, in particular, to a control method of an electromagnetic device, a control system of an electromagnetic device, and an electromagnetic device. Background technique [0002] At present, the function of the induction cooker is to simply heat, that is, the alternating magnetic field is generated by the current passing through the coil. When the magnetic field lines in the magnetic field pass through the bottom of the iron pot, the magnetic field lines are cut, which generates countless small eddy currents, making the iron pot Its own iron molecules rotate at a high speed and generate collision and friction to generate heat to heat the food in the pot. [0003] The multi-load wireless power supply system proposed in the related art mainly converts mains power into high-frequency alternating current, and outputs high-frequency alternating magnetic field energy through the transmitti...
