摘要

即使是单个光伏(PV)电池的遮阳也会显著降低组件的功率。本文提出了一种解决方案，通过将Ćuk双向转换器与光伏模块集成，可以允许所有模块在各自的最大功率点运行。这是通过应用新的控制策略来实现的，该策略可以在不同的遮光水平下适当调整变流器的占空比。通过SIMULINK/MATLAB仿真和实验验证了该方案的有效性。

Control of integrated Ćuk converter and photovoltaic modules for maximum power generation

Shading of even a single photovoltaic (PV) cell can significantly reduce the power of a module. This paper presents a solution by integrating Ćuk bi-directional converters with PV modules which can allow all modules to operate at their individual maximum power points. This is achieved by applying the novel control strategy which enables proper adjustment of converters' duty ratios under different shading levels. The proposed scheme was verified in SIMULINK/MATLAB simulation and in experiment.
