| Abstract | Two-level inverters are the most basic subset of multi-level inverters (MLIs). As the number of output levels increase, total harmonic distortion reduces and the performance level increases. In traditional MLI topologies, more number of power devices are involved to obtain higher order inverters which increases cost, complexity and volume. By minimising the use of power component, overall cost can be reduced. In this study, a MLI structure is proposed with minimised power components. The reduction of components are achieved through single and double source modules such as single source and single switch, single source and switch with parallel diode and double source and single switch with parallel diode. In the proposed MLI structure, the switches are reduced by half in comparison with cascaded MLI and hence the percentage in reduction of switches increase as the levels increase. For better appreciation, the proposed topology is compared with the current state of the art in MLI. This topology is modelled and simulated using LTspice and MATLAB/SIMULINK R2014 a. The prototype is designed and validated for seven and nine levels experimentally. |

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.
