Power Electronic Transformer-Enabled Wireless Electric Vehicle Charging Systems an Integrated Approach

This research explores the integration of Power Electronic Transformers (PETs) in the context of wireless electric vehicle (EV) charging systems, by designing a typical inductive power transfer (IPT) system comprising AC power input, a power factor corrector (PFC), an inverter, and a primary compensation network feeding a transmitting coil. The receiving side includes a receiving coil, secondary compensation, a rectifier, and the EV battery. PETs, also known as Solid-State Transformers (SSTs), offer significant advantages in such applications by replacing traditional line-frequency transformers and providing functionalities like voltage regulation, fault isolation, and improved power quality for smart energy and Electric Vehicles. The PET advanced control capabilities optimized the efficiency and dynamic performance of the entire wireless charging link, enabling bidirectional power flow and enhanced grid integration for future EV charging infrastructure.
