Wireless charging of lighting gadgets using low Q resonant coupling

Abstract

Wireless power transfer for lighting gadgets on a table top using low Q resonant coupling is realized. Using distributed capacitances across the transmitter and receiving coils and the inherent resistances of the wires, the coil acts as a tuned LC circuit. Since the secondary coil is resonant with the primary coil at a common frequency of 400 KHz, power is transmitted between the coils in the near field range and an efficiency of 20% is achieved.
