This work proposes a CUK–SEPIC converter for photovoltaic water pumping application with maximum power point tracking (MPPT). For this a new hybrid gravitational search algorithm (GSA)–particle swarm optimisation (PSO) based MPPT method is proposed. The recent power electronics based CUK–SEPIC converter provides identical output with positive and negative ground reference. The novel converter minimises the ripple present in the supply current and provides optimum PV power extraction from solar module by integrating input and output magnetic cores of inductor. The proposed model is practically tested under changing solar insolation by employing switch reluctance motor for water pumping applications.

基于CUK-SEPIC转换器的新型光伏发电系统，采用混合GSA-PSO算法，采用MPPT进行水泵应用

这项工作提出了一种用于光伏水泵应用的CUK–SEPIC转换器，具有最大功率点跟踪（MPPT）。为此，提出了一种基于MPPT的新型混合重力搜索算法（GSA）–粒子群优化（PSO）。最近基于电力电子技术的CUK–SEPIC转换器可提供相同的输出，带有正负接地基准。这种新型转换器通过集成电感器的输入和输出磁芯，最大程度地减少了电源电流中的纹波，并提供了从太阳能模块中提取的最佳PV功率。通过在水泵应用中使用开关磁阻电机，在改变的日照下实际测试了该模型。
