| Abstract | Since space vector modulation offers superior performance with respect to other modulation techniques, it is important to establish the sequencing strategy which is best suited for variable-frequency AC drives. The characteristics of regular direct-direct (DD) and inverted direct-inverse (DI) sequencing strategies are investigated both analytically and experimentally. The two strategies are compared with respect to the current ripple, the current spectrum, and the commutation losses. It was found that DD sequence offers superior performance for the majority of loads, such as induction motor drives. For other types of inverter loads, with small or leading power factors, the optimal modulation strategy consists in using the DI sequence when the output voltage is low and the DD sequence if the modulation index is between m(M) and 1. For best results, the switch-over point M has to be evaluated as a function of load and inverter design.<> |

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.
