Research on Impedance Conversion Networks and Optimum Efficiency Tracking for Voltage-Fed ICPT System
As a new kind of power transmission method,wireless power transmission (WPT) is getting more and more attentions.Inductively Coupled Power Transfer (ICPT) is a common form of WPT.For a voltage-fed ICPT system,Impedance Conversion Networks (ICN) is always needed to improve the efficiency,loading capacity and the stability of the system.A kind of ICN for voltage-fed ICPT system is proposed and analyzed in this paper which makes the voltage gain of the ICPT system to be constant even when the loads are changing,and it is especially fit for the use in which the output voltage is constant,such as mobile phone,laptop computer,tablet and so on.In this paper,the efficiency and characteristic of ICPT system were analyzed and the optimum efficiency tracking method of ICPT system is proposed.Finally,corollary and the method in this paper were verified through the experiment.
