| Abstract | High efficiency, high power density and wide constant power region are all the required functions of the traction motor and drive in electric vehicle applications. However, these requirements are mainly dependent on the output line voltage utilization of the motor drivers. Generally, electric vehicle use over-modulation to increase voltage utilization under constant output voltage of battery. A six-step voltage control method without current control loops is proposed to increase output torque and power of IPMSM at middle and high speed region. The relation between generated torque and both amplitude of DC-link voltage and phase leading voltage angle of six-step voltage is derived carefully on this research. The proposed method is analyzed by Fourier series for mathematical derivation. Moreover, the efficiency of motor and its drive are improved due to the current harmonics and switching losses of PWM are reduced by the six-step voltage control. The proposed motor drive consists of two power modules controlled by single DSP. The front end is a DC-DC converter connected to battery to generate a variable voltage with fast response according to the motor speed. The second stage is an inverter which provides vector control and the proposed six-step voltage control for IPMSM. Finally, some simulated and experimental results are made on a 6kW IPMSM to show the correctness of the proposed analysis 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.
