Photo Voltaic Application of Two Switch Enhanced Gain Buck Boost Converter in Buck Mode

The aim of this paper is to introduce a high gain buck boost converter in buck mode, which is designed to be highly effective in power applications such as Photovoltaic systems. This converter topology is constructed by integrating a boost topology, consisting of an inductor and switch, with a zeta configuration. This combination helps to achieve a high voltage transformation ratio, making it an ideal choice for applications that require a significant amount of current. Additionally, the converter is capable of operating in both buck and boost modes. This paper assesses the effectiveness of the proposed high gain buck-boost converter in buck mode with Photovoltaic system. Buck mode is selected because of its ability to exhibit high gain along with considerable amount of current, which is suitable for applications like battery charging and lightning applications. Hardware results of the converter with both DC supply and Photovoltaic system are also included in the paper.
