Abstract

Provided are an electromagnetic heating circuit, a control method and apparatus for an electric device, and an electric device. The circuit includes at least two resonance modules, at least two switch modules, an inverter module, a gating module, an oscillation drive module, a voltage processing module, and a control module. The switch module includes a fixed terminal, a movable terminal, a first position terminal, and a second position terminal. The at least two switch modules are in one-to-one correspondence with the at least two resonance modules. The fixed terminal of each switch module is connected to a corresponding resonance module. The inverter module is connected to the first position terminal. The gating module is connected to the second position terminal. The oscillation drive module is connected to the gating module. The voltage processing module is connected to the oscillation drive module. The control module is connected to the inverter module, the voltage processing module, the gating module, and the at least two switch modules. By means of the technical solution provided in embodiments of the present disclosure, when some of the resonance modules in the electromagnetic heating circuit are in a heating state, it can also be detected whether a pot is placed at positions corresponding to other resonance modules that are not in the heating state.
