| Abstract | This paper presents two power system architectures where distributed-input parallel-output (DIPO) DC-DC converters are controlled to achieve their equal input voltages while harvesting electricity from their distributed power sources at a system optimum power point; the system optimum power point is the maximum power drawn from the distributed power sources while their voltages are kept uniformly distributed1 2 even though their individual peak powers are different. With proper uniform input voltage distribution control, near maximum use of the power sources is achieved by employing only one maximum power tracking (MPT) controller instead of multiple MPT controllers dedicated for their respective power sources. Provided that the maximum power point voltages of the input power sources are similar, the resulting system and control architectures offer near-maximum power transfer with a lower parts count. The two DIPO power converter architectures are also described in detail: one with the battery-dominated output voltage bus and the other with the regulated output voltage bus. A feasibility study using computer simulation has successfully validated both power architectures and their control concepts for optimum energy harvesting and maximal fault-tolerances for failures of more than one power source or 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.

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.
