Design On The Receiving System Of Wireless Power Transmission Based On Resonance

Wireless power transmission technology(WPT)is one of the hotspots.Its security is consistent with the FCC,IEEE and CCC standards.WPT can completely solve wiring messy of electrical appliance and bring more convenience to people.Three pairs of transmitting and receiving coils were wired and measured.The resonant frequency of the coil was obtained.The design of the transceiver coil has a good direction.As the transmission distance increases,the transmission efficiency at the high resonant frequency increases and then decreases,and at the low resonant frequency,the transmission efficiency decreases gradually.And the frequency division occurs when the transmitting and receiving coils are in resonance.As the transmission distance increases,the two resonant frequencies move closer to the center frequency and the frequency splitting disappears.The receiving module of WPT system was designed and simulated based on the resonant frequency.The simulating results show the receiving module designed in the paper was satidfied with the specifications.The efficiency of the receive module is about 66.6%.
