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 MSC VLSI - XLL, MSC VLSI - L YL, MSC VLSI - LLZ and MSC VLSI - XYZ. The goal of the proposed research is to design a converter with high voltage gain ratio. The key advantage of MSC VLSI 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.
