| Abstract | This paper presents a new modification for the most-common, simple, and well-known three-phase voltage source inverter (VSI). In this modification, each one of the six transistors conducts for 150deg instead of the usual 180deg or 120" conduction modes. For a wye-connected load, the output phase-voltage becomes a seven-level, 12 Steps waveform-which is closer to the sinusoidal waveform-than the 6-step one. This results in a 50% reduction of the total harmonic distortion (THD), 75% reduction of voltage distortion factor (DF), and the lowest order harmonic (LOH) becomes 11 rather than 5. A comprehensive study for the three modes of conduction is proposed, and a comparison with other types of VSIs, like the neutral point clamped (NPC) and the multilevel inverters (ML1) is also carried out. Simulation and experimental results show the contribution of the proposed strategy. Index term-voltage source inverters, 150deg conduction mode, 12-Step waveform, seven-level inverter, total harmonic distortion. |

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.
