Performance Analysis of Various Compensation Topologies in Wireless Power Transfer

Abstract

Wireless charging is a steady, appropriate and secure method of powering and charging Electric vehicles (EV). Inductive coupling is the most common method of Wireless Power Transfer (WPT). The performance of an inductively coupled energy transfer system for moderate operating distance between the transmitter and receiver coils can be improved by utilizing resonant circuits in both primary and secondary side. Compensation topologies are essential in magnetic resonant coupling WPT system to improve the Power Transfer Efficiency over certain distances and is being promoted for EV charger applications. This paper presents various compensation topologies for wireless power transfer and compare the results from both simulation and validates the same using experimental setup to support the concepts.
