Abstract

In order to avoid the oscillation of duty ratio perturbation method and make full use of solar arrays power, after establishing a model of the solar array, analyzing its input and output characteristics, and discussing the concept and principles of peak power tracking (PPT), we use fuzzy controller to modify three parameters of PID controller to modify the step of duty ratio to track the maximum power point of solar array. The simulation results show that the method can quickly and accurately track the MPP, decreases the oscillation and improve the efficiency of energy conversion of solar array.
