MAGNETIC-COUPLING RESONANT WIRELESS ENERGY TRANSMISSION AND RECEIVING CIRCUIT

Title:

MAGNETIC-COUPLING RESONANT WIRELESS ENERGY TRANSMISSION AND RECEIVING CIRCUIT

Document Type and Number:

WIPO Patent Application WO/2015/131794

Kind Code:

A1

Abstract:

A magnetic-coupling resonant wireless energy transmission and receiving circuit, comprising: a resonance circuit (1), the resonance circuit (1) comprising a resonance coil (L1) and resonance capacitors (C1, C4); a rectifier circuit (2), an input end of the rectifier circuit (2) being electrically connected to both ends of the resonance capacitor (C1); an energy storage capacitor (C2), both ends of the energy storage capacitor (C2) being electrically connected to an output end of the rectifier circuit (2); and a DC-DC convertor (3), an input end of the DC-DC convertor (3) being electrically connected to both ends of the energy storage capacitor (C2), and an output end of the DC-DC convertor (3) being electrically connected to a rechargeable battery (B). The magnetic-coupling resonant wireless energy transmission and receiving circuit can save electric energy, and has high charging efficiency.
