Abstract: Wireless battery charging of electric vehicles is been under development to commercial scale in recent past. Inductive Power transfer has established usage in wire-less power transfer. This paper proposes an improved dual power transfer system for wireless battery charging for electric vehicle charging application. The working principle being obtaining resonance between filter inductance and capacitive transfer element and thus improving power transfer capability and efficiency of the charging system. A 3kW dual power transfer battery charging system is designed and implemented. The equivalent model of circuit is simulated in MATLAB/SIMULINK. The dual power transfer system reported a high efficiency with high switching frequency and performs better under misalignment than the inductive power transfer System.
