Abstract :
This paper presents a new step-up DC/DC converter topology. The converter is intended for applications that require a high gain of the input voltage and galvanic isolation, i.e. power conditioning systems for alternative energy sources such as fuel cells. The operation principle of the converter is explained by help of a steady state analysis. Simulation results are presented and analyzed. Finally, the experimental results are provided and a modification possibility of the proposed converter is discussed.
