This paper describes a new inductive charger circuit fur opportunity charging of electric vehicles in the future. The coupling transformer utilized features a very large air-gap that is comparable to the cross-sectional dimensions and hasn't heen considered in previous studies. The study proposes tu fully compensate the large leakage inductance of the windings using series capacitors and tu control the charging power using an additional d.c.-d.c. chopper at the output stage. The eddy current losses associated with the leakage flux and voltage stresses in the circuit are shown to he acceptable. The working principle of the proposed circuit is experimentally tested.
