| Abstract | Hybrid electric vehicles and battery electric vehicles use three-phase power inverter(s) to drive electric traction motor(s) using pulse width modulation (PWM) methods. Various types of PWM schemes provide the same fundamental component of the output voltage but different harmonic components. This results in different harmonic flux linkage and harmonic current, causing different machine copper loss and core losses. An accurate model of the current total harmonic distortion (THD) for various PWM schemes can provide an insight into which PWM method can minimize the electric machine copper loss and core losses, hence, increasing the overall fuel economy of the vehicle system. Most of HEV/BEV products use interior permanent magnet (IPM) synchronous machines for traction. Literature review shows that existing methods of calculating the current THD are only valid for an inductance load or a surface permanent magnet synchronous machine with equal d- and q-axis inductances. Error occurs if the method is applied to an interior permanent magnet synchronous machine with unequal d- and q-axis inductances. This paper investigates a method that can accurately calculate the current THD for IPM machines. The accuracy of the proposed method is verified by computer simulations. |

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.
