| Abstract | Modern power conversion electronic devices must not pollute the power distribution system and keep a unit power factor. Furthermore, their design must be size and cost effective. It is also expected that all new designs should have an entirely digital control by 2008. We present a series resonant power converter that is driven by a pulse density modulation (PDM) strategy combined with a three level hysteresis controller to adjust output power. This approach is suitable for a fully digital control design. A single digital signal controller is used to monitor and control the whole system. By the means of simulations and experimental results, it has been shown that a traditional sixteen-level PDM approach helps to maintain a near unity power factor and a low total harmonic distortion. However, such converter can only deliver sixteen output power levels. Design parameters are such that a 25 kHz signal is delivered to the load. Research presented here shows that using the proposed hysteresis control the PDM series resonant converter is able to deliver a wide output power range with 1 W resolution (range from 5 to 360 W). The mean output power error is less than 0.3 %. This strategy can be combined to other PDM approaches to obtain a better power factor and an improved THD within desired power range |

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.
