Abstract This paper represents one kind of high-power wireless power transfer (WPT) system with low cost, easy debug and high efficiency. Firstly, conducting angle, LC filter parameters and impedance transformer problem of high-power E-class amplifier are analyzed. Then, equivalent circuit model of magnetic resonance WPT system is established considering four mutual inductive coils. Furthermore, a calculation method of equivalent input impedance is proposed. Finally, aiming at minimizing device power loss and restricting device breakdown and input voltage, a WPT system, which can transfer 3kW power over 22cm with 85% efficiency, is built up to verify the method.
