| Abstract | In this paper a new structure for asymmetric multilevel converters is presented. The new topology is consisting of N series-connected of two interconnected multilevel converters per phase. The presented circuit is an optimized multilevel converter with minimum DC voltage sources and switches. The investigated topology can generate a large number of levels (odd and even) without increasing the number of switches and DC voltage sources. For this structure a new algorithm for calculating the levels of DC voltage sources is proposed. Also a complete analysis is given for calculating the harmonic distortion and THD. The proposed converter has higher efficiency because the number of switches is reduced and the devices which can be switched at low frequency. Then for showing the ability of the proposed converter, we use this converter as the core of a DVR, which is based on this converter. This DVR has been modeled and the simulation results show that the DVR can solve power quality problems such as: voltage sag, voltage swell, unbalanced and distorted voltages |

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.
