A fuzzy-logic controlled PV powered buck-boost DC-DC converter for Battery-Load system

In this paper, a fuzzy logic controlled buck-boost DC-DC converter powered by Photo Voltaic (PV) for Battery-Load system is presented. General design of the converter-load system is performed using Matlab/Simulink. In the FLC, different fuzzy membership functions are used and the results are compared with each other. The complete converter-load system has been developed, analyzed, and validated by the simulation. Performances have then been evaluated in detail for different operation conditions. The effects of the different fuzzy membership functions and the PV module parameters on the controller are also compared.
