Dynamic analysis of solar powered two-stage dc-dc converter with MPPT and voltage regulation

The renewable energy sources are playing a dominant role in many power generation applications all over the world. Moreover, the solar energy is superior due to its low maintenance cost and cleanliness. However, the solar power generation highly depends on the environmental conditions. This paper explores the utilization of the solar power with the two-stage dc-dc converter specifically designed for distributed grid applications. The proposed power system includes the boost converter in the first stage and the high gain converter in the second stage. The boost converter is implemented with the perturbation & observation and the Sliding Mode Control based Maximum Power Point Tracking control strategies. The second stage high gain converter can fulfill the excellent load and line regulations. The exhaustive MATLAB/Simulink results are presented for both the converters.
