| Abstract | Traditional dynamometers, such as hysteretic dynamometers, eddy current dynamometers, mechanic dynamometers and waterpower dynamometers, may consume lots of fuels and electrical energy while working, which causes the energy waste. Also, these dynamometers should be equipped with additional radiators to keep the dynamometers cool. A type of novel dynamic power dynamometer scheme is presented based on PWM rectifier and direct torque control (DTC) technology for induction motor in this paper. The proposed dynamometer can operate in both motoring and generating states by DTC of induction motor, which ensures the swift torque response of the dynamometers. Three-phase PWM technology enables the bidirectional flow of the energy. PWM rectifier can not only provide DC link voltage for the induction motor, but also feed back the energy generated by the dynamometer to AC mains, which guarantees both current sinusoid and unit power factor. This scheme decreases the harmonic disturbance to the AC mains, saves the energy sources, and cut the cost of purchasing radiator. In order to validate the feasibility of the scheme, an experimental device based on the DSP and intelligent power module IPM is designed. Experimental results indicate that the novel dynamometer has an outstanding dynamic and static performance |

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.
