DC microgrids have surged in popularity owing to the seamless integration of sustainable energy such as fuel cells, solar photovoltaic, wind and hydro power. Because of the comparatively modest output voltage of these energy sources, there is a need for highly efficient DC-to-DC converters to facilitate the integration with DC microgrids. This paper introduces a Front End Interleaved Split Duty Switched Inductor-Capacitor (SDSLC) based High Boost DC-DC Converter. SDSLC Converter achieves voltage gain amplification without the need for voltage multipliers, transformers, and voltage lifting methods. This design choice simplifies both the construction and operation. The primary advantage of this converter resides in its ability to operate switches with two distinct duty ratios, enabling ultra voltage gain is achieved without necessitating high duty ratios. SDSLC converter is theoretically deduced in continuous conduction mode. Detailed analysis at steady state of SDSLC Converter by these two distinct duty ratios is provided. The development of the SDSLC Converter is implemented in PSIM with 20V to 300V, 100W, and its accuracy is confirmed through theoretical validation.
