A novel high gain non-inverting, single switch configurations of modified SEPIC DC-DC converter for high-voltage/low-current renewable energy applications
A non-inverting, single switch with voltage lift switched inductor module high gain configurations of the modified SEPIC converter is discussed in the paper for high voltage and low current renewable energy applications. Based on the VLSI module position, modified SEPIC converter are classified into four configurations as MSCVLSI - XLL, MSCVLSI - L YL, MSCVLSI - LLZ and MSCVLSI - XYZ. The goal of the proposed research is to design a converter with high voltage gain ratio. The key advantage of MSCVLSI configurations is: 1) single switch topologies which have a simple control strategy, 2) continuous input current and non-inverting boosted output voltage. The mathematical analysis and Matlab/Simulink results validate the functionality of four configurations of the modified SEPIC converter.
