| Summary: | Inductive based wireless battery charging (WBC) is gaining popularity in the contemporary electric vehicle industry. As the internal resistance of the battery is continuously changing throughout the charging profile, the charging power needs to be controlled. Phase shift control is mostly used to control the power flow between the transmitter and the receiver of the resonant converter in inductive WBC. During the phase shift control, the semiconductor switches to loose zero voltage switching (ZVS) or zero current switching (ZCS), thereby impacting the efficiency of the resonant converter. To address this, an asymmetrical clamped mode control is proposed for a resonant converter in this chapter. The proposed approach ensures that the power semiconductor switches attain ZVS while meeting the charging power requirements. To validate this, a MATLAB/Simulink model of inductive WBC with the proposed control strategy is developed, and the obtained results are presented. © 2023 selection and editorial matter, Dharavath Kishan, Ramani Kannan, B Dastagiri Reddy and Prajof Prabhakaran; individual chapters, the contributors. |
