摘要	in a photovoltaic grid connected system, the switching losses and conduction losses can be reduced effectively by using the three-phase bidirectional dual Buck/Boost converters controlled by half period SVPWM, based on the SVPWM control strategy, this paper introduced a fuzzy PI control to increase the stability of the system which reduced the overshoot and adopted LCL filters with strong inhibition ability of high frequency harmonics to realize the grid-connection of system unit power factors. Using Matlab to carry out an simulation experiment to the system and the simulation results showed that the closed loop system could effectively realize the grid-connection of system unit power factors, improve the stability of the system and the quality of the grid connected current and enhance the robustness of the system.
