Abstract

Recently, electric vehicles have become the preferable alternative over conventional vehicles because of rise in fuel price and pollution. Wireless charging system can make electric vehicles even more attractive. In this paper, a circuit using inductive power transfer (IPT) technique is proposed to transfer power of 1 kW wirelessly. Contactless coils are designed to operate at frequency of 15 kHz. FEM based results are presented for the same. Electromagnetic circuit is designed to transfer the power over a distance of 10cm with maximum efficiency. A closed loop model is proposed to keep output power constant. The complete system is then simulated and results are presented to analyze the efficiency. The overall efficiency obtained is 88.5 %.
