全天从太阳能电池板中提取最大的能量，在运行时提供最大的功率，这有助于实现太阳能电池板成本和客户收益之间的早期分解。最大功率点跟踪受到电力电子转换器拓扑结构及其控制系统能力的限制。错误的拓扑选择可能导致次优操作和完全缺乏可跟踪性。几种转换器拓扑被用来提高太阳能电池板的效率，通过提取太阳能组件的最大功率。这些拓扑结构的工作原理是负载和太阳能组件之间的阻抗匹配。本文讨论了非隔离型变换器拓扑结构及其在不同负载下最大功率点跟踪的比较。本文提出了这些拓扑的某些限制。本文还讨论了特定拓扑结构对最小无源元件数量和不同负载范围的适用性。
Extracting the maximum energy from solar panels throughout the day deliver the maximum power at runtime that helps to attain early breakdown between solar panel cost and benefit for customer. Maximum power point tracking is limited by capabilities of power electronics converter topologies and its control systems. Wrong selection of topology can leads towards sub optimal operation and total lack of tractability. Several converter topologies are used to enhance the solar panel efficiency by extracting the maximum power from solar modules. These topologies work on the principle of impedance matching between load and solar module. In this paper non-isolated converter topologies and their comparison using different loads for maximum power point tracking has been discussed. Certain limitations of these topologies have been presented in this paper. Suitability of particular topology with respect to minimum number of passive components and different load ranges has also been discussed in this paper.
