The photovoltaic(PV) power generation systems become a convenient and promising solution for electric power production by directly transforming solar radiations into electricity. This paper proposes current sharing in paralleled connected positive super lift luo converters (PSLLCs) for standalone photovoltaic system. Paralleled connected converters results in generation of higher output current. But the problem associated with such types of converter is that no equal sharing of output current takes place between individual converter modules in presence of parameter mismatches. Hence to ensure equal sharing of output current a new current sharing scheme without a dedicated current sharing controller is proposed. To regulate output voltage lag-lead compensator is used. The performance of lag-lead compensator is compared with lead and lag compensator through MATLAB/Simulink.
