| Abstract | In today's electrical drives, the use of more than three-phases to implement the electrical machine stator winding is a frequently adopted provision to enhance system power rating and fault tolerance. In VSI-fed electrical machines, multi-phase windings are adopted in both their symmetrical structures (with n equally distributed phases, supplied by a single n-phase inverter) and in their multiple three-phase arrangements (with two or more displaced three-phase windings, each supplied by an inverter). On the other hand, in CSI drives, based on synchronous motors and Load Commutated Inverters (LCIs), the only multi-phase topology practically used consists of two three-phase windings, displaced by 30 electrical degrees, each fed by an LCI. This paper investigates an alternative, symmetrical multiphase LCI drive topology based on a five-phase motor supplied by a five-phase inverter. Both the motor and the inverter are accurately modeled in the Matlab/Simulink environment to study their combined behavior through numeric simulations, both in normal and faulty operating conditions. Simulation results are presented in order to highlight the pros and contras of the proposed topology with respect to the existing ones, taking performance and fault-tolerance features into account. |

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.
