Overcurrent and overvoltage protection circuit, electromagnetic induction type wireless power supply system and cooking appliance
Provided are an overcurrent and overvoltage protection circuit, an electromagnetic induction type wireless power supply system and a cooking appliance. The overcurrent and overvoltage protection circuit includes a current detecting unit that outputs a current detection value by detecting a resonance current of a resonant transmitting unit a voltage detecting unit that outputs a voltage detection value by detecting a resonance voltage of the resonant transmitting unit and a main control unit including a current detecting end and a voltage detecting end, and the current detecting end is connected to an output end of the current detecting unit, the voltage detecting end is connected to an output end of the voltage detecting unit, and when the current detection value exceeds a preset current limit and/or the voltage detection value exceeds a preset voltage limit.
