In tandem with the penetration of PHV as well as EV, wire-less power supply system in parking towers have become important subjects. In parking towers, EV and PHV are charged on the traveling pallets, supply power is to be transmitted from the building to travelling pallets. In this paper, high frequency link AC-AC converter for non-contact power supply system in parking tower is newly proposed and its basic operation performance have been demonstrated from computer aided simulation and experiment.
