Abstract
The selection of battery charger technology provides a higher platform for electric vehicles (EVs) in the market. Recent trends are towards the inductive power transfer (IPT) based EV battery chargers (EVBCs) as it is a convenient and safe solution over conventional plug-in EVBC. The currently available IPT system utilizes soft switched power electronic converters while maintaining a near sinusoidal current for a limited power transfer range. In this paper, an improved ZVS IPT topology and it’s switching pattern is proposed. ZVS is achieved by optimizing the classical series compensation and additionally, an auxiliary network is employed to achieve wide-range performance independent of loading conditions. The proposed concept is verified by using MATLAB/ SIMULINK based simulations for resistive and battery load. An efficiency of 92.5\% is achieved with ZVS for a full dynamic power transfer range of 300 W to 3000 W.
