| Abstract | Z-source energy conversion is a recent concept introduced for adding voltage-boost functionality to the otherwise buck-only dc-ac inverter. The same concept can equally be extended to other converter topologies including the indirect ac-ac matrix converter, where only a single Z-source impedance network needs to be inserted to its intermediate dc-link. Because of such a simple insertion, topological extension of the indirect Z-source matrix converter is viewed as trivial with its operating states easily deducible from its existing dc-ac counterpart. In contrast, modulation of the extended indirect ac-ac entity is judged as nontrivial and not at all obvious if advantages like buck-boost flexibility, minimum commutation count and ease of implementation are to be attained simultaneously, in addition to sinusoidal input and output quantities commonly set as objectives for ac-ac energy conversion. Attaining these advantages simultaneously is no doubt important since any shortfalls or compromises would make it even harder to justify for those passive components introduced to the otherwise “all semiconductor” indirect matrix converter. Bringing forth these advantages by unveiling related optimal modulation theories is therefore a relevant investigation that is pursued now to better present the indirect Z-source matrix converter as an attractive alternative for ac-ac buck-boost energy conversion. Findings presented here on have already been verified in simulation or experimentally using a laboratory-constructed prototype. |

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.
