Abstract

A contactless power transfer system for electric vehicles needs to have a high efficiency, a large air gap, good tolerance to misalignment in the lateral direction and be compact and lightweight. In this paper, a new 1.5kW transformer has been developed using novel H-shaped core which is more efficient, more robust to misalignment and lighter than previous rectangular core to satisfy these criteria, and its characteristics are described. An efficiency of 95% was achieved across 70mm mechanical gap. The modeling of iron-loss in the equivalent circuit is also presented. The calculated efficiency using this model shows good agreement with experimental results.
