Design and Benchmark of Front-end Voltage Control for Wireless Power Transfer

MSc thesis of Zian Huang

In recent years, the Wireless Power Transfer (WPT) system has become more and more popular due to its prominent advantages, especially for Electrical Vehicle (EV) charging. The WPT systems are required to follow the EV battery charging profiles, thus more and more voltage control methods with distinctive characteristics are proposed and studied. The goal of this thesis report is to conduct a comprehensive benchmark of the front-end voltage control solutions. This thesis report focuses on the front-end voltage control solutions including the front-end buck converter and the phase shift control based on the primary inverter. The conclusions not only suggest more efficient voltage control solutions but also introduce harmonic calibration methods to improve the calculation 
accuracy.
