| Abstract | In this paper, a digital-controlled multi-phase electronic current sink is proposed. The wide Safe Operation Area (SOA) MOSFETs are used as the power dissipating device, which are regulated to the saturation region by filtered PWM gate signals. Due to the inherent limitation of switching frequency and sampling rate in digital systems, interleaved multi-phase PWM scheme is proposed to provide active current ripple mitigation. The power stage and signal conditioning peripherals are designed and modeled; the digital controller is implemented to provide regulation for constant current and pulsed current sink modes. The digital signal controller dsPIC33FJ64GS606 is used to provide four-phase interleaved high-precision PWM and real time control for the prototype. The experimental test results indicate that the proposed system performs well in the steady-state and dynamic testing, and is applicable to future digitalized testing equipments. |

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.
