Abstract | The authors deal with the problem of controlling of single phase active filters. Some algorithms for active filters controlling are well known today, but some of them can't be used in case of single phase filters. For example the PQ Theory (Theory of the Instantaneous Reactive Power) is excellent for three phase solutions, but for single phase solutions it can't be implemented. The main challenge in the single phase controlling method is to get the fundamental harmonic function in a proper magnitude and phase. The authors proposed a simple and fast method, which is based on the LMS algorithm (“Least Mean Square” algorithms are a class of adaptive filters). This method can be easily implemented also in 8-bit microcontroller units only with the need of sum and multiplication instructions. Because the same algorithm can be used also for converter control synchronization, the authors constructed a test device detecting mains phase voltage zero-crossings with an 8-bit ATmega8L processor, where the algorithm was implemented. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
