A Novel High Gain Configurations of Modified SEPIC Converter for Renewable Energy Applications

A novel configurations of a non-isolated Modified SEPIC Converter with two Voltage Lift Switched Inductor (MSCVLSI) modules namely MSCVLSI-XYL, MSCVLSI-LYZ and MSCVLSI-XLZ are presented in the paper. The key features of these configurations are, 1) high voltage conversion ratio, 2) single controlled switch, 3) high-value input inductor to smooth the input current, 4) maximum utilization of input source, 5) continuous input current. With these notable features, proposed configurations are more convenient for high voltage renewable energy applications to boost the low voltage of photovoltaic array/fuel cell. The feasibility of these converter configurations are verified by mathematical analysis and simulation results. MSCVLSI configurations are simulated for 250 W resistive load and at 50 kHz switching frequency.
