A Study of a Non-Isolated DC-DC Converter Based on High Voltage Gain

G. Jayalaxmi, R. V. S. L. Kumari

Abstract


This article implements a best non-isolated DC-DC
Converter for solar photovoltaic system-driven DC MicroGrid
applications through high voltage gain methodology. At first, a
hybrid boosting converter with bipolar voltage multiplier method is
proposed and studied for photovoltaic-based DC MicroGrids. But
the cost and functionality of this converter are a big problem. To
eradicate these problems with a proposed modified SEPIC
converter and this converter is studied for producing high voltage
gain. Formerly performance of hybrid boosting converter and
modified SEPIC converter are simulated in PSIM software. As a
final point, the simulation results are compared and verified that
the modified SEPIC converter suits best for solar photovoltaic
system-based DC Microgrids to provide essential power levels to
the residential electrical loads.
