摘要

在光伏(PV)应用中用作dc-dc优化器的非逆变降压-升压(NIBB)转换器需要在非常宽的转换比率和功率水平范围内运行。传统的控制方法通常包括复杂的模式切换和针对不同工作模式设计的补偿器，这通常会导致模式转换期间的干扰甚至潜在的不稳定。本文提出了一种统一的滑模控制方法，以实现平滑的模式转换，同时保证在宽工作范围内具有良好的动态性能。在20v ~ 60v输入、40V输出的NIBB上进行了仿真和实验验证。

Unified Sliding-Mode Control of Non-Inverting Buck-Boost Converters

Non-inverting buck-boost (NIBB) converters used as dc-dc optimizers in photovoltaic (PV) applications are required to operate over a very wide range of conversion ratios and power levels. Conventional control approaches typically include complex mode switching and compensators designed for different modes of operation, which often lead to disturbances and even potential instabilities across mode transitions. This paper proposes a unified sliding mode control approach in order to achieve smooth mode transitions, while at the same time ensuring excellent dynamic performance over a wide operating range. The proposed approach is verified in simulation as well as experimentally on a 20V-to-60V input, 40V output NIBB case study.

期刊介绍： COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
