Abstract
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.
