| Abstract | The brushless dc motor (BDCM) has been widely used in industrial applications because of its low inertia, fast response, high power density, high reliability, and maintenance-free reputation. It is usually supplied by a hard-switching pulse width modulation inverter, which normally displays relative low efficiency since the power losses across the switching devices are high. In order to reduce the losses, many soft switching inverters have been designed. However, these inverters have such disadvantages as high device voltage stress, large dc link voltage ripple, discrete pulse modulation, and complex control scheme. This paper introduces a novel resonant pole inverter, which is unique to a BDCM drive system, and is easy to implement. The inverter possesses the advantages of low switching power loss, low inductor power loss, low device voltage stress, and simple control scheme. The operation principle of the inverter is analyzed. Simulation and experimental results are proposed to verify the theoretical analysis. |

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.
