摘要

Based on the output characteristics of photovoltaic (pv) battery and the analysis of MPPT control the-ory, a model of MPPT control system with pv power generation of Boost circuit is researched. The operation princi-ples of each sub-module in the model are analyzed. And the simulation model of the whole system is built by Simu-link software. Taking photovoltaic array STP0950S-36 as an example, the simulation verifies that the maximum pow-er tracking can be well realized by MPPT control system and the changes of exterior environment can be responded quickly and the efficiency of photovoltaic power generation can be improved effectively.%基于光伏电池输出特性及MPPT控制原理的分析，研究了基于Boost电路的光伏发电MPPT控制系统的模型，并分析了该模型中各子模块的工作原理，并应用Simulink软件搭建了整个系统的仿真模型。以光伏阵列STP0950S-36为例，仿真验证了所研究的MPPT控制系统能很好地实现最大功率跟踪，并能快速响应外界环境的变化，有效提高光伏发电的效率。
