Maximum power point tracking strategy of disturbance Solar Panels output current

摘要

Because the output of solar panels is influenced by external environment easily, and in order to ensure the energy generated by solar panel can be used as much as possible, so the maximum power point tracking technology is particularly important. In this paper, to achieve the maximum power point tracking of the solar panel output through the flyback converter. Using the method of perturbation the output current of the converter, though adjusting the duty ratio of flyback converter switch makes solar panels to the maximum power output. It has the advantages of simple structure, low cost and high efficiency. This control strategy can be applied to a system that has variety of energy supply.
