| Abstract | The paper describes an investigation of inverter fault-tolerant vector control for permanent-magnet synchronous motor (PMSM) driven by a fault-tolerant inverter. The inverter is a topology-modified inverter with fault-tolerant capability, which can be configured as the standard 3-phase 6-switch inverter under the inverter health condition and reconfigured as 3-phase 4-switch inverter under the inverter fault condition respectively. By analyzing operating principle of a fault-tolerant inverter and the mathematic model of PMSM, current and voltage character of three fault-tolerant method (phase A fault-tolerant, phase B fault-tolerant and phase C fault-tolerant) in the fault-tolerant converter are investigated and there is a conclusion that three phase currents of three phase stator windings of PMSM can be controlled effectively by controlling two phase currents of them randomly. Then, a novel vector control scheme is proposed to drive PMSM based on the fault-tolerant inverter. The strategy is feasible and simple. Simulation results show the validity of the proposed method. |

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.
