Tracking Frequency Resonant Coupling Energy Wireless Transmission Research

Abstract:

The problem of transceiver coil resonance frequency detuning is solved tentatively on resonant coupling energy wireless transmission in this paper. The circuit model of the wireless transmission system of the resonant coupling electrical energy is first studied, the relationship between the parameters of the system and the transmission efficiency of the various parts is analyzed, and yhe studies have shown that the change in the amount of the transmitting coil inductance greater impact on the transmission efficiency, while the receiving coil inductance change in the amount of efficiency small, and thus the proposed phase locked loop frequency tracking technology, to ensure that the transceiver coil resonant frequency to ensure that the transmission efficiency of the system. The feasibility of the design frequency tracking system is verified with the experimental results.
