Performance Analyses of Boost and Interleaved Boost Converters used in Wireless EV Charging Systems

Hazardous emissions and greenhouse gases are produced by the burning and overuse of fossil fuels. Electric Vehicles (EVs) provide solutions for the conservation of conventional energy resources, pollution reduction for a safe environment, and zero-emission vehicles. EV charging can be done in two ways, either wired or wireless. Wired charging has barriers like high cost, limited consumer knowledge, limited driving range, etc., when compared to wireless charging. Moreover, wireless charging can provide automated charging, which is more safe and convenient. A wireless EV charging system employing an Interleaved Boost Converter (IBC) as the DC-AC converter is discussed along with its performance analysis. A performance comparison of conventional Boost Converter (BC) with IBC is done, which shows that the structure of the IBC reduces current ripples and losses, thus improving the overall system efficiency. The simulation results are presented to prove the effectiveness of IBC in the application of Electric Vehicle Wireless Charging Systems (EVWCSs).
