A Development of Class E Converter Circuit for Loosely Coupled Inductive Power Transfer System
In this paper, the authors present an Inductive Power Transfer (IPT) system design using a class E converter circuit. The class E converter is used to drive a nonlinear load and theoretically it offers 100% efficiency. To be specifically, the performance of IPT system at 1MHz operating frequency and 9V DC supply voltage is analyzed. Voltage doubler rectifier and Darlington circuit are proposed in this paper to maximize output power. Moreover, to ensure the resonant inductive coupling in IPT system, capacitor compensation is also proposed in this work.
