基于Boost电路的光伏发电MPPT仿真研究

Smulation of MPPT about Photovoltaic Power Generation of the Boost Circuit

太阳能是地球上取之不尽、用之不竭的能源,光伏发电是目前世界上发展前景最好的一门发电技术。但光伏发电效率较低,为了解决这一问题,本文对光伏发电的最大功率跟踪进行了研究。结果表明,当太阳能电池板带负载时,通过调节占空比,利用BOOST电路变换,实现阻抗匹配,能使太阳能电池工作在最大功率点,并使用MATLAB仿真验证了其结果。

Solar energy is inexhaustible, inexhaustible energy on earth, photovoltaic power generation is the development prospect of the best in the world a generation technology. But photovoltaic efficiency is low, in order to solve this problem, in this paper, the photovohaic maximum power tracking is studied. The result shows that when the solar panels on load, by adjusting the duty ratio, the use of the BOOST circuit transformation, realize the impedance matching, working in the maximum power point of solar battery, and the result was verified using MATLAB simulation.
