Abstract
This paper presents the modeling and analysis of bidirectional power transfer in electric vehicles by employing a wireless inductive charging circuit with LCL compensation. A Maximum Efficiency Point Tracking (MEPT) control scheme using adaptive frequency tuning method and phase shift control is proposed in this work. MEPT control is used to optimize as well as maximize system efficiency by regulating output voltage keeping input power minimum. The system is analysed using MATLAB/SIMULINK. System energy efficiency over varying load and coupling conditions are analysed. The results show that the system gives a dc-dc efficiency of 94% at full load condition.
