The advancement of technology led to the utilization of electrical energy. Renewable sources like photovoltaic
(PV) systems play a vital role in the generation of electricity. But the output voltages of these sources are very low. This
paper proposes a soft switching (ZVS) high voltage gain step-up converter for increasing the output voltages of these
systems. The proposed system is developed in such a way that the gain of the converter is high, voltage stress across the
switches is low and the switching losses are also less. The proposed system is simulated in the MATLAB/SIMULINK
environment.
