Design A Couple Inductor DC-DC Converter to Increase Conversion Ratio and Efficiency Using For Solar Energy System

This paper introduce a new step-up DC-DC converter with high step-up conversion ratio. DC analysis is presented and the static characteristics are expected to show that the static conversion ratio exhibits a high voltage boost, the converter still stable operating at narrow cycle duty. The proposed converter ratio at the same duty cycle D is (1+nD) time higher than the classical Boost, where n is the transformer ratio. Compared to quadratic converters the proposed topology has also one transistor and three diodes, but it eliminates two reactive elements. The converter is simulated and real tested on the physical couple i
