摘要：
in recent years, as energy and environmental problems, solar energy utilization has obtained Rapid development. This paper analysis and compares the main technical issues of the solar power system and proposed a Improved Buck-Boost Circuit based on soft-switching technology as a DC/DC converter, then designed a fuzzy logic controller of two grid-connected PV system to achieve the maximum power point tracking. On the basis of Improved Buck-Boost Circuit, built the MPPT control model based on perturbation and observation method and fuzzy control method. By Matlab/Simulink simulation to verify the feasibility of the algorithm, the results shows the characteristics and advantages of the maximum power tracking applied to fuzzy control system.
