Abstract

This paper compares different topologies of non-isolated high conversion ratio dc-dc converter for fuel cell application. These converters transfer the low dc voltage of fuel cell to high dc voltage in dc link. In this study, ripple content of both input current and output voltage are compared and discussed. A comparison and discussion of the voltage and current stress on the switch are also presented in this paper. Study carried out on this paper intends to choose the best converter for fuel cell application. The proposed converter has high conversion ratio with reduced voltage and current stresses on the power semi conductor switches when compared to the conventional boost converter. This analysis helps to choose the best converter for fuel cell system and also to other renewable energy systems. Simulation is conducted over MATLAB/ simulink.
