Wireless Power Transfer Structure Design for Electric Vehicle in Charge While Driving

In the last years the interest on the inductive charging of electric vehicles is grown according to the increase of the electric vehicle market. In this paper a novel approach to the design of a charge while driving wireless power transfer structure is proposed with several improvements with respect to the previous works on the same topic. Different suitable solutions are analyzed and a new hybrid topology for the capacitive compensation is proposed. The rules to correlate the real system with a down-scaled model are given and applied to a scaled wireless power transfer prototype used to validate the proposed theoretical approach.
