DESIGN AND IMPLEMENTATION OF TRANSIENT CONTROL PI BASED BOOST CONVERTER

This paper proposes a new boost DC-DC with PV connected system converter with a high voltage conversion ratio for the renewable energy source. To get a high voltage gain, the proposed converter consists of the new two stage cascaded structure and has two voltage conversion processes. Due to the new structure and voltage conversion process, it has the higher output voltage gain at the same duty cycle than the conventional boost converter. To verify the PI performance and effectiveness the proposed circuit was analyzed and tested by the MATLAB 2015a simulator. The calculated power steady state time of the proposed circuit was 0.02s and the proposed circuit had the 3.5 times higher conversion ratio at the half duty cycle than the conventional boost converter. Therefore, the superior voltage conversion ability of the proposed circuit is proved from the simulation results.
