چکیده

This paper proposes an ultrahigh step-up DC-DC converter composed of two boosting stages, a coupled inductor and switched capacitors. Advance features of the converter consist of its high voltage gain, low voltage stress on its switches, continuity of its input current and existence of a common ground between the source and load. In addition, it needs an inductor and a coupled inductor with smaller sizes in comparison to the compared references which lead to its performance with higher efficiency. Among the compared converters, the proposed converter boosts voltage with higher voltage gain per different turns ratio of the coupled inductor. Analysis of the converter has been performed for its main switching states to validate its quality and quantity factors. A prototype is built in order to experiment its performance per different conditions and evaluate the analysis. The experiments are rated for input voltage, output voltage and output power equal to 25V, 400V and 150W respectively.
