| Abstract | This study deals with a position sensorless brushless DC (BLDC) motor-driven solar photovoltaic (PV) fed water pump. A technique based on the back electromotive force (back-EMF) zero crossing is proposed for sensorless operation of the BLDC motor. The back-EMF is derived from the difference of line voltages. Thus, a requirement of neutral potential is eliminated. In addition, the proposed drive avoids the use of phase current sensors. The speed is automatically adjusted according to the available peak power from the PV array. The devices of voltage source inverter, used to feed the BLDC motor pump, are switched at fundamental frequency. This leads to minimised switching losses. The responses of PV fed pumping system with the proposed drive are observed under various operating conditions. The suitability of the proposed topology is demonstrated through the hardware implementation. |

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.
