| Abstract | This paper proposes a novel control scheme which possesses four-phase PWM dimming control loop for backlight inverter. We adopt four-phase PWM dimming control circuit to control the brightness of twelve lamps. Each phase can control four or two lamps. Circuit architecture is full bridge phase-shift circuit which can improve the total efficiency of the driving circuit. From the experimental results, we verify the performance that four-phase PWM dimming control will be better than the conventional single phase one. It can uniform lamp current, brightness and luminance. |

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.
