Abstract

This paper present an input-series output-parallel active-clamp-forward converter for low voltage dc/dc xEV application. The converter can achieve ZVS turn-on for all switches. An accurate small signal model of the converter which includes the effect of leakage inductance is given and controller design based on modeling is described. Experimental and simulation results from a 3.2kW, 100kHz prototype are presented in order to verify the validity of the converter operation and the designed control parameters.
