Abstract : pResearch into Wireless power transfer, its applications and adoption is currently growing at a rapid rate. Wireless Power Transfer (WPT) provides a lot of advantages and serves as a solution to the drawbacks of wired power transfer techniques. Research nowadays is focused on developing an inductive power transfer module for transferring power wirelessly. In order to improve the efficiency and the range of power transfer, new coil structures and design schemes for wireless power transfer have been introduced. This paper provides a comparative study of a WPT circuit with a boost rectifier circuit and another with a single-stage boost rectifier circuit, with focus on reducing switching losses and complexity. The DC side inductor and switch of the boost circuit is replaced with an AC side inductor to overcome the disadvantages of boost circuit. For each circuit explained in this paper, Matlab simulation results of output voltage, current and efficiency are analyzed and presented. © 2018 the Author(s). All rights reserved./p
