Proportional resonant controlled high gain step-up converter system with improved response

Abstract

In recent days the step up converters used for commercial & industrial applications should produce high gain with ripple free output voltage. The step up converters are connected between PV and DC loads, these should have capacity to produce high gain, and it serves as a good interface between load and source. In our work a suitable methodology is adapted to reduce the ripple in output voltage. The proposed method uses the Closed Loop system (both PI and PR controller) with coupled inductor and a switched High gain step up Converter with Cascade filters. The results of PI and PR controllers are compared to find best output.
