摘　　要：光伏发电系统的单Boost电路输出的电压和电流纹波较大,会影响发电系统的可靠性和稳定性,因此提出一种基于交错并联Boost电路的改进型光伏发电系统。在MATLAB/Simulink模块中搭建仿真模型,仿真结果表明,交错并联Boost电路可以有效减小电流和电压的纹波,证明其可以在并网光伏发电系统中发挥积极作用。The output voltage and current ripple of single Boost circuit of photovoltaic power generation system are large,which will affect the reliability and stability of the power generation system.In this paper,an improved photovoltaic power generation system based on interleaved and parallel Boost circuit is proposed.The simulation model was built in MATLAB/Simulink module.The simulation results show that the staggered Boost circuit can effectively reduce the ripple of current and voltage,which proves that it can play an active role in grid-connected photovoltaic power generation system.
