Maximum Power Point Tracking of PV Systems Using Fuzzy Controller with Boost DC/DC Converter
This paper presents a fuzzy-logic-controlled boost DC/DC converter for photovoltaic (PV) system . The tracking algorithm changes the duty ratio of the converter such that the PV model voltage equals the voltage corresponding to the MP point at that solar insolation. The main difference between the method used in the proposed MPPT system and other techniques used in the past is that the MPPT method is fuzzy based and is used to directly control the dc/dc converter, thus reducing the complexity of the system. The proposed fuzzy tracking effectiveness is demonstrated through the simulation results, and are compared with the conventional controller based system.
