Abstract

A wireless power supply system for a cooking appliance includes a power transmission device and a power reception device. The power transmission device includes a transmission coil and a coil driving circuit coupled to the transmission coil and configured to drive the transmission coil to generate an alternating electromagnetic field and vary a resonance voltage of the transmission coil. The power reception device includes a reception coil matching the transmission coil and configured to sense the alternating electromagnetic field to generate a varying induction voltage signal that varies according to the varying resonance voltage and a communication and demodulation circuit configured to demodulate the varying induction voltage signal to output demodulated data.
