| Abstract | Utilization of solar energy is one important action to decelerate the observed climate change and to ensure the availability of energy in the future. Reliable solar-energy systems composing of solar arrays and their interfacing converters are of prime importance but known to have certain operational constraints causing reliability problems. The paper investigates a real current-fed converter for the maximum-power-point (MPP) tracking purposes in solar-generator systems. The current-fed converter is implemented from the conventional voltage-fed converter by applying the duality transformation methods. The investigations show clearly that the input-voltage-controlled current-fed converter can operate without constraints in all the regions of solar generator I/U curve but the operation is limited to the voltages lower than the MPP voltage if any output control is used. The theoretical findings are verified with experimental current-fed superbuck converter sourced by a real solar array. Similar information cannot be found from the public literature. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
