| Abstract | In this study, a new high step-up non-isolated three-port DC–DC converter is proposed. A bidirectional buck–boost converter is used to interface photovoltaic battery and non-isolated load port. Compared to the other three-port converters, the presented topology has fewer component counts, which is the main merit of the proposed converter. The output voltage of the converter can be increased by using a three winding coupled inductor, a diode and a capacitor. Furthermore, since both main switches are turned on with zero voltage switching, switching losses is reduced and the efficiency of the converter is improved. Maximum power point tracking and maintaining the output voltage at a suitable level during the charging and discharging of the battery can be achieved by a simple controller. Moreover, according to the load power demand, three power flow paths will occur. The operation principle will be described in detail for three modes. Finally, the experiments with 400 W, 100 W, 40 V/400 V are implemented to verify the effectiveness of the converter. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
