Abstract: Photovoltaic energy generation is considered to be one of the most promising sources of renewable green energy because it is clean, inexhaustible and requires less maintenance. However, the efficiency and gain obtained from PV systems are not satisfactory. The output of a single PV cell is about 0.6V and hence high gain dc-dc converters are required to step up the voltage. Solar energy for off-grid power sources is preferred to be the best solution for rural households, which don’t have an uninterrupted power supply, across India. PV power generation for DC appliances will prove to be beneficial as the DC-AC conversion is eliminated. This paper discusses three topologies of DC-DC converters that act as an interface between PV and the load. The topologies investigated in this paper include Boost, Luo, and Luo-buck converters. The configuration of these converters is studied and simulated in MATLAB/SIMULINK. The operative parameters such as conversion gain, output voltage ripple, output current ripple, stress across the semiconductor devices and input current ripple are computed and the results are compared. From the results, it is found that the Luo-Buck DCDC converter results in better performance compared to the other two topologies. The theoretical results are verified in simulation.
