| Abstract | The high penetration of renewable electrical energy sources into the power grid is highlighting the problem of harmonics. Eliminating line current harmonics is taken very seriously in HVDC transmission where the ac/dc/ac conversion process is the source of mains pollution. The need for high efficiency and low harmonic content for grid-connected inverters is high. The oldest topology still used in hvdc is the line-commutated 3-level thyristor inverter, characterised by low losses due to the inherent low switching rate. The high content of harmonics and the bulky passive filters to minimize them, makes this solution non-attractive and has let the way to new topologies and modes of operation of inverters. In this paper though it is suggested to keep the 3-level thyristor grid connected inverter for its robustness and high efficiency and replace the bulky passive filters with switched capacitor filters. A new active filter, the DSSC circuit is investigated here and its ability to cancel a band of lower harmonics is reported. |

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.
