Contactless charging systems are becoming the most convenient and safest way to refill Electric Vehicles (EVs) batteries. Wireless Power Transfer (WPT) has been successfully adopted in EVs high power applications to efficiently deliver energy over a relatively large air gap.

Abstract

Contactless charging systems are becoming the most convenient and safest way to refill Electric Vehicles (EVs) batteries. Wireless Power Transfer (WPT) has been successfully adopted in EVs high power applications to efficiently deliver energy over a relatively large air gap. In order to predict the realistic performance of an EV wireless charger, the impact of real components tolerances and semiconductor devices losses must be considered. In this paper, a model for the analysis of the influence of semiconductor devices losses and of resonant devices parameters uncertainty is discussed. The model is validated through PSIM simulations of a 3.7kW/85kHz WPT system.
