Abstract

Wireless Power Transfer (WPT) technology has been increasingly applied in power supply for portable devices such as mobile phones and electric vehicles (EVs). Conventional WPT systems are usually designed to supply specified loads with only single voltage/current output. In many practical applications, however, electric appliances usually require different voltage and current levels. In this work, a load-independent multi-output WPT system with only one primary coil (transmitting coil) and one secondary coil (receiving coil) is proposed. By connecting parallel double-T resonant circuits to the common ac terminal of the receiving coil, multiple constant de outputs can be achieved. Furthermore, by adjusting the parameters of the individual resonant circuit, each output channel can generate different voltage level flexibly. Theoretical analysis and experiment results of a laboratory prototype confirm the effectiveness of the proposed WPT system.
