| Abstract | The objective of this work is to show that the theoretical limit of the constant power speed range of the recently proposed dual mode inverter control (DMIC) driving the permanent synchronous machine is infinite. To reach such goal, the average value of the voltages and currents in the dq rotating reference frame are used to model the DMIC/PMSM system. The principle is shown to be the same of the vector control with field weakening operation (VCFW). However, in VCFW the voltage limit circle is given by the maximum output voltage of the VFI and therefore shrinks fast as speed increases. In the DMIC, on the other hand, the voltage limit circle is a result of the contribution of DC link voltage, the back emf, and the induced voltage provided by the derivative of the on-phase currents and it shrinks slower as speed increases compared to VCFW. The conclusion is that there is no inherent speed limit of CPOR when PMSM/DMIC control scheme is used because the voltage constraint is eliminated. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
