Abstract | Based on the central-limit control algorithm for the parallel connected converter system, two improved dynamic current distribution control methods are introduced: the programmable current distribution control (PCDC) and the maximum current limit control (MCLC). In PCDC, the ratio of the output current of each converter to the total output current can be programmed according to the desired application objective while the output voltage remains regulated. In the MCLC, all converters in the system may not be turned on at the same time depending on the load conditions. The steady-state analyses and design consideration of the PCDC controlled converter system are presented. The steady-state current distribution error (CDE) between the output current of converters is used as a criterion to evaluate the system performance. The design consideration of choosing proper loop compensators, and scaling factors to reduce the CDE is also introduced. These two schemes can be combined to achieve better system performance, which increase the life-time, reliability, and efficiency of the overall converter system. |

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.
