LCL Topology Based Single Stage BoostRectifier Topology for Wireless EV Charging

摘要

Research into Wireless power transfer, its applications and adoption iscurrently growing at a rapid rate. Wireless Power Transfer (WPT) provides alot of advantages and serves as a solution to the drawbacks of wired powertransfer techniques. Research nowadays is focused on developing an inductivepower transfer module for transferring power wirelessly. In order to improvethe efficiency and the range of power transfer, new coil structures and designschemes for wireless power transfer have been introduced.This paper providesa comparative study of a WPT circuit with a boost rectifier circuit and anotherwith a single-stage boost rectifier circuit, with focus on reducing switchinglosses and complexity. The DC side inductor and switch of the boost circuitis replaced with an AC side inductor to overcome the disadvantages of boostcircuit. For each circuit explained in this paper, Matlab simulation results ofoutput voltage, current and efficiency are analyzed and presented.
