Abstract
DC Microgrid has got attention due to wide use of DC energy sources. For this purpose, high gain boost converter is proposed. Modified switched inductor is used to boost the output voltage at the load. Compared with the traditional boost converter the converter has high voltage gain. The converter has two switches and is operated using single control reducing the complexity of the circuit. The steady state analysis in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) is elaborated. Further, the comparison is made with similar topologies. Loss analysis and effect on the efficiency of the converter by considering the non-idealities is detailed in the paper theoretically. Simulation is carried on PLECs software. Theoretical results and simulation study are in agreement with each other.
