| Abstract | In this paper a direct finite-state predictive flux and torque control of an induction motor drive system fed by four-switch three-phase voltage inverter was discussed. This specific inverter topology can be used after faulty inverter leg isolation from an electric motor under single IGBTs open-circuit faults. To overcome a significant problem related to the four-switch inverter topology, namely capacitor voltage unbalance in DC-link, a solution based on the voltages measurement was developed. In the proposed approach, depending on a motor drive operation point, in order to achieve a high drive performance a weighting factor of a cost function term related to capacitor voltages balance is adapted. To confirm the proposed method, simulation results were presented under a wide range working conditions of an induction motor drive system. |

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.
