Abstract | CSI fed induction motor drives are employed in medium voltage high power applications. One of the major limitations of these drives is the injection of current harmonics into the source, due to the presence of fully controlled ac to dc converter at input stage. There is an increased demand by the industry to modify these drives to meet IEEE 519 standards. This paper proposes a novel CSI drive, in which two identical multilevel inverters are used as active filters, one at the input end and another at the motor terminals, with common dc bus. The active filter at input end provides necessary active current to maintain dc bus. Such an arrangement will ensure sinusoidal input current, sinusoidal motor current and motor voltages. Since the active filter has very high bandwidth, it will be possible to meet the harmonic specifications as per IEEE 519 standards. The proposed drive is simulated and the results are presented. The experimental implementation is in progress. The proposed configuration promises a better alternative compared to other conventional methods like use of passive filters or multi pulse rectifiers at the input stages in terms of cost and 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.
