| Abstract | This study presents a position sensorless surface-mounted permanent-magnet synchronous generator (SPMSG) and its application in powering DC microgrid. The derated characteristics of a PMSG with different AC–DC converters under brushless DC generator (BDCG) mode and the conventional switch-mode rectifier (SMR) mode are first comparatively assessed. Then a PMSG followed by three-phase three-switch Vienna SMR is established. Good operation performance is achieved via the proposed robust current and voltage control schemes. Second, a position sensorless control scheme based on observed extended back electromotive force (EMF) for the SPMSG followed by Vienna SMR is developed. The generation characteristics are enhanced by the developed starting and back-EMF angle tuning schemes. Third, a single-phase three-wire load inverter with the proposed novel robust waveform tracking control scheme is developed to yield good AC 220 V/110 V output voltage waveforms under unknown and non-linear loads. Some experimental results are provided to demonstrate the operation performances of the established SPMSG system in conventional generator with fixed output voltage and wind generator. More specifically, the BDCG mode and the SMR mode for operating a PMSG are experimentally evaluated. |

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.
