Abstract This study analyzes the reverse recovery phenomenon of a semi-bridgeless rectifier (SBR) in an inductive power transfer (IPT) system for electric vehicles. Ideally, the reverse recovery phenomenon does not occur in a diode rectifier, however, in practical systems, the reverse recovery phenomenon occurs even when the SBR operates like a diode rectifier due to high operating frequency. Therefore, a practical analysis of operation modes for SBRs is presented in this study, considering the reverse recovery phenomenon, and the requirements for SBR switches are proposed. The analysis results are experimentally verified using a 3.3 [kW] IPT system prototype to which three different types of switches are applied.
