Compact pulse position control-based inverter for high efficiency inductive power transfer to electric vehicle

Abstract

A compact high efficient inductive power transfer (IPT) topology based on pulse position control is proposed for wireless charging of electric vehicle. Near-field wireless charging is efficiently achieved by the resonance-enhanced IPT technique. The system sustains high power transfer efficiency under contingency in misalignment of pickup coil and load variations. The performance evaluation of the proposed system under the occurrence of anticipated perturbation in load and mutual inductance is studied numerically. Experimental results from the developed prototype corroborate the theoretical and simulated results discussed in the proposed study.
