“…It is worthwhile to point out that right now the system input voltage is lower than 400 V, which is widely used in the commercialised battery chargers forEVs. Therefore if the grid voltage is 220VAC, a step‐down front‐end power factor correction (PFC) [15] is needed instead of the traditional boost‐type PFC [16].…”

This study proposes a design and development of a wireless power transfer system to charge the battery in electric vehicles. A parallel-parallel topology is adopted to realise 10-15 cm-distance power transfer using the resonance theory. Finite-element method is used to extract the coil parameters. The advantages of the proposed design compared with the previous similar research are (i) low operational frequency (42 kHz) which avoids the electromagnetic interference to the onboard automotive electronics equipment and (ii) low electric stress to the semiconductor switches through using zero-voltageswitching technique. A 2 kW prototype to charge 200 V battery was built to experimentally verify the theoretical analysis. The overall system efficiency is ∼ 86%.
