| Abstract: | This paper introduces the equivalent circuit, mathematical models and the output characteristics of the PV array at first, and then uses Matlab/Simulink to build dynamic simulation models. The Boost circuit is used to achieve the maximum power point tracking and the duty ratio control is realized with the incremental conductance method. The paper analyzes the principle and the function of each module in the single-phase and three--phase systems and observes the output waveform changes under different environmental temperature and illumination intensity, and finally verifies the validity and correctness of the system. |
