Abstract

Positive-output super-lift Luo converters (POSLCs) with low switching losses are the subject of this paper's analysis, design, and regulation. Due to their ability to boost voltage at higher levels, converter switching devices are rarely put under extreme voltage conditions. The input voltage to an active switching device is typically lower than the output voltage. This means that low-quality components are used to build the converter. The proposed conversion can be a good choice in PV micro converter applications requiring high voltage gain. The continuous conduction mode of the converter and its underlying operating principle and steady-state analysis are described. The converter's basic principle is demonstrated by constructing a working hardware prototype, which is tested in the lab. The outcomes demonstrate the benefits of employing an Arduino for voltage control. It has also been found that the converter achieves maximum efficiency of 95.3% at full load. The results were confirmed using MATLAB / Simulink in POSLC design with MPPT which is in agreement with the experimental results.

独立光伏应用超升力LUO转换器的高效设计、分析与实现

具有低开关损耗的正输出超升力罗变换器(POSLCs)是本文分析、设计和调节的主题。由于它们能够在更高的水平上升压，变换器开关器件很少被置于极端电压条件下。有源开关器件的输入电压通常低于输出电压。这意味着使用低质量的组件来构建转换器。在需要高电压增益的光伏微型变换器应用中，该变换器是一个很好的选择。介绍了变换器的连续导通方式及其基本工作原理和稳态分析。通过构建工作硬件样机，演示了转换器的基本原理，并在实验室进行了测试。结果证明了使用Arduino进行电压控制的好处。还发现该变流器在满负荷时达到95.3%的最高效率。利用MATLAB / Simulink对POSLC进行了MPPT设计，结果与实验结果一致。
