| Abstract | A power grid connected inverter is operated in synchronized with reference ac voltage at the point of common coupling. The robust phase detection is indispensable for inverter operation in harsh condition. The phase detection system is required to be immune to unbalance and distortion of ac voltage waveform. A complex coefficient filter can discriminate positive and negative frequency component in input signal, which cannot be attained for conventional real coefficient filter. This paper studies the applicability of infinite impulse response digital filter with complex coefficient to a phase detection system by phase locked loop (PLL) for three phase ac system. The frequency characteristics and dynamic response of the filter is assessed, and series connection of band pass and notch filter is evaluated to satisfy both required performance. The phase detection system is implemented in the digital processor hardware and the applicability of the complex coefficient filter is 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.
