Self-sustaining Hybrid Renewable Energy DC Micro Grid System with Ideal Energy Superintendence for AC Load Operation

The paper presents a proposed design of SEPIC with high voltage gain for sustainable energy applications. The suggested circuit is structured by combining the standard SEPIC with a magnifying module. Hence the converter profits from various assets that the specific converter has, like uninterrupted input current. Also, high voltage gain and input current continuity makes the proposed converter applicable for sustainable energy sources. The altered SEPIC converter (MSC) gives higher voltage gain compared to standard SEPIC and recently addressed converters with single-controlled switch. The analysis of voltage gain in continuous current mode (CCM) and discontinuous current mode (DCM) is carried out by considering the non-idealities of semiconductor devices and passive components. The preference of semiconductor devices depending on voltage- current rating is put forward along with the designing of reactive components. The numerical simulation and experimental work is done and the results demonstrate viability of the MSC concept and theoretical analysis.
