Abstract | High-performance interior permanent magnet (IPM) machine drives using a current source inverter (CSI) are being studied for hybrid electric vehicle applications. This paper focuses on extending the constant-torque and constant-power operation ranges of an IPM machine by utilizing the voltage-boosting capability of the CSI. An equivalent circuit model of the IPM machine, including the inverter ac filter capacitors and the motor core-loss resistor, is presented and used to ensure the tracking of the torque-producing current of the PM machine to the commanded value under all operating conditions. A novel control strategy is proposed to achieve both minimum system losses and high system performance over the entire operating range, including the field-weakening region. Simulation and experimental results are presented to validate the functionality of the boost mechanism, the effectiveness of the equivalent circuit model, and the proposed control scheme. |

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.
