In this paper, filter-integrated LCC compensation is proposed. Since electromagnetic interference (EMI) is one of the issuses of wireless power transfer (WPT) system for electric vehicles (EVs), EMI filters are required for the inverter, which is the source of noise. In addition to the filter, the wireless charging system uses an LCC topology to compensate for series resonance. These additional circuits increase system size and volume. To simplify the WPT system, a circuit that operates as an impedance matching network and filter in differential mode and an EMI filter in common mode is proposed. The effect of the proposed method was experimentally verified by applying it to a 22kW WPT system.
