Abstract

In this study, an inductive power transfer (IPT) charger for electric vehicles is proposed to improve the entire system efficiency and power density by eliminating the DC-DC converter in the secondary side. In the proposed IPT charger, the DC-link voltage is adjusted according to the coupling coefficient through cascade buck-boost converter in the front-end side, and the bridgeless rectifier performs the charging of battery. The control algorithm for the proposed IPT system is theoretically explained, and the validity of the proposed system is verified by informative simulation.
