Novel Step up Converter with Multi Winding Transformer for Fuel Cell Applications

G. Venkateswarlu, Dr A. Sudhakar

Abstract: This project presents a new step-up converter for fuel cell applications. The step-up converter is an electronic device which is used to boost-up the voltage levels. Fuel cell converts chemical energy into electrical energy at low levels which can be supplied to remote areas. The low level voltages can be step-up to higher levels by applying converters. The voltage gain and efficiency of coupled inductor based step-up converter can be improved by replacing coupled inductor with multi winding transformer. The above design is implemented and verified in MATLAB simulink platform.
