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