| Abstract | A large scale Thermoelectric Generator System (TEG) has temperature distribution for both heat source and heat sink, leading mismatch power loss. The insertion of power conditioner witch has impedance matching ability between TEG and a load has a potential to recover the mismatch power loss of the system effectively. The practical maximum power point tracking (MPPT) conditioner for TEG with the size of 30times60 $mm^{2},$ which can be used up to 30 W has been developed. The power conditioner is composed of Buck-Boost converter, internal power supply, and microcontroller. The microcontroller controls the virtual conductance of the load to match the internal conductance of the connected thermoelectric modules. The effect of MPPT power conditioner insertion is evaluated using the experimental TEG system, which composed of four thermoelectric module (TEM) strings. We confirmed each MPPT power conditioner connected in parallel maintains optimum operating condition. The results suggest that introducing MPPT power conditioner has a potential to reduce mismatch power loss and improve load matching ability of TEG system. |

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.
