Abstract

Photovoltaic (PV) modules under different solar irradiances have generally the distinct maximum power points. In this paper, a circuit topology for obtaining the respective maximum powers from the above PV modules is investigated. Simplified double cascade boost choppers are proposed and a control scheme to derive the respective maximum output powers from individual PV modules is discussed. Furthermore, the Maximum Power Point Tracking controls on the starting operation, on the solar irradiance change and on the load fluctuation are confirmed by several experiments.
