| Abstract | Most of the current sensorless control schemes for BLDC (Brushless DC) motor are based on full-bridge driver. However, half-bridge driver draws a lot of attention due to its simpler structure, smaller occupied volume, lower power loss, easier control scheme and lower production cost, and it has been successfully utilized in several applications. Inspired by these applications, this paper presents novel designs for sensorless BLDC motor based on half-bridge driver circuit with buck modulator. For different applications, two specific back EMF detection methods: terminal voltage detection method and line voltage detection method, are proposed. The simulation results verified the validity of the proposed design for sensorless BLDC motor, and by comparisons we further pointed out different characteristics and possible applications of the two back EMF detection methods. |

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.
