Abstract :
A new dc-dc converter topology suitable for renewable energy sources such as photovoltaic panels or fuel cells is proposed in this paper. The converter which is a derived from Z-source converters uses coupled inductors to provide isolation and high conversion ratios. A big advantage of this converter is low switch voltage rating. A detailed analysis of a 25 V / 400 V dc, 300 W system is given along with preliminary simulation results.
