A Flexible Design of Secondary-Side Compensation Circuit for Inductive Power Transfer

Secondary-side compensation method of inductive power transfer (IPT) systems has been proposed in order to simplify transmitter circuitry while realizing load-independent voltage. In this work, we investigate how to design a secondaryside compensation circuit that can convert the output voltage to an arbitrary value. Simulation and experiment results show that the output voltage can be changed only by the design of the compensation circuit. In addition, we also discuss the relationship between transformation rate and output voltage stability, efficiency.
