Abstract

Advancements in power electronics have aided in the development of inductive power transfer technologies by providing transmitter coil drivers and converters for conditioning the power received at the receiver coil. But the use of traditional two-stage circuit with half wave or full wave rectifiers and boost converter at the receiver side may be inefficient, as it reduces the total power delivered to the load. As an alternative, single-stage boost rectifier can be used, which is compact and more efficient. This paper introduces an efficient wireless charging system based on resonant magnetic coupling that contains single-stage boost rectifier at receiver. Single-stage rectification and boosting is made possible by the bidirectional conduction capability of MOSFETs. The system is designed and simulated in PSIM software. The overall power transfer efficiency of the system is analyzed for different coupling factors of the inductive links and for different loads.
