Comparative Analysis of a High Efficiency S–S and P–S Compensation Topologies for Inductive Power Transfer EV Battery Charging System

Wireless power transfer (WPT) is a superior and more efficient method of charging electric automobiles as compared to conductive charging. Hence, the technique will be crucial in further advancing this technology in the future. Wireless power transfer (WPT) has several obstacles, with the efficiency and capacity of power transmission being the most prominent. Compensation topologies play a crucial role in improving the efficiency and power transmission capability of wireless power transfer (WPT) systems. This study examines the electrical properties associated with wirelessly charging an electric car using coil systems configured in Series-Series (S–S) and Parallel-Series (P–S) arrangements. The parameters that have been assessed are validated using MATLAB simulations of a comparable system. Once all the necessary information has been presented, an assessment is conducted to compare S–S topologies with P–S topologies using analytical and simulation research methods.
