| Abstract | This paper discusses a systematic method to analyze and design the control of parallel active power filter (PAPF). The discussion begins with a universal two-port representation of power stage of PAPF. With the power stage represented by this two-port block, a general control diagram based on current detection is proposed. Different control schemes can be obtained from this general control diagram with different gains of each detected current. For simplicity, this paper discusses four kinds of gains, including zero pass, full pass, high-frequency pass and low-frequency pass. A systematic procedure is then proposed to generate all possible 64 possible control schemes, and the criteria are derived to verify the validity of each control scheme. According to these criteria, there are 4 valid ones among the 64 possible schemes. Only one of these 4 control schemes has been known previously and used in practice. The other three new practical control schemes are further analyzed in detail. Further more, the authors found that these valid control schemes are not independent, and their internal relations are revealed. This conclusion is really helpful for electrical engineers to analyze and design the control of APF. The derived new control schemes are verified by both time-domain computer simulations and experimental tests on hardware prototypes. |

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.
