| Abstract | A new high gain step-up dc–dc converter based on modified active switched-inductor (MASL) and switched-capacitor (SC) is proposed in this study. The proposed converter is based on the classical boost topology, in which the inductor is changed by the proposed MASL cell. This new cell allows the addition of more than two switched-inductors (SLs) to the classical boost topology, which is the most significant limitation of conventional active SL. Additionally, in the proposed converter, the output capacitor is replaced by an SC cell, increasing still more the voltage gain of it, which can be higher than 20 without using transformers or coupled inductors, and with lower voltage stress on the semiconductors and high efficiency. The principle of operation, theoretical static and dynamic analysis, design methodology and comparison with other non-isolated topologies present in the literature are approached in this study. The performance of the proposed converter is validated by interesting experimental results obtained from a 200 W prototype with an input voltage of 20 V, an output voltage of 400–600 V, switched frequency at 50 kHz and peak efficiency of 95%. |

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.
