Design and implementation of a multi-output inductive charger for electric vehicles

Multi-output chargers are widely used in various electronic devices due to their benefit in terms of cost, efficiency and space for installation. On the other hand, Inductive Power Transfer (IPT) has been applied increasingly in electric vehicle (EV) since it is more convenient and safer as compared to conductive chargers. However, researches on multiple output chargers using IPT system for EV charging applications are rarely presented. This paper proposes a new method in an IPT system, which can charge several batteries of EV independently at one time by using one full bridge inverter at the primary side and several compensation tanks at both primary and secondary side. The theoretical analysis demonstrated, design steps, and simulation results are presented to verify feasibility and validity of the proposed method.
