Abstract

This paper presents the implementation of zero voltage switching technique in an interleaved boost rectifier circuit. This converter circuit uses a parasitic capacitor of the MOSFET switch to bring the voltage across the switch to zero. For this purpose, an auxiliary circuit has been provided consisting of two switches and a LC tank circuit. The main application for the converter includes high voltage battery charging in electric vehicles. A comparison of efficiency has been made between conventional interleaved and interleaved resonant circuit to show the performance improvement of the proposed circuit.
