摘要

Mid-range low-power wireless power transmission systems using resonant-inductive coupling have recently been in use for powering a variety of household gadgets. A modified resonantly coupled system for a wireless power transmission system using coaxial helical solenoid coils is presented, using distributed parameters predominantly at high frequency. The proposed system is reduced using circuit transformations, and the operating power transfer efficiency under varying conditions of source and load are derived. The model is tested with an experiment consisting of a home lighting utility load for the resonant frequency of 1.2 MHz. The experimental results are in close agreement with the proposed analytical model for varying distances between the transmitter and receiver. A comparison of the operating power transfer efficiency of the proposed model with resonantly and inductively coupled models for varying distances between the transmitter and receiver is presented. Maximum power transfer efficiency by matching source and load resistances is simulated using the RF Toolbox on the proposed, resonantly coupled, and inductively coupled models. The simultaneous conjugate-matching technique for increasing the power transfer efficiency to near 100% is also presented.
