Abstract | A new three-level ZVS-PWM DC-DC converter operating in a wide load range is introduced. It is used for high-voltage and high-power applications and has as its main features: zero-voltage-switching (ZVS) from no load up to full load, operation at constant frequency, regulation by pulse-width modulation (PWM), and low RMS current stress upon power switches. Its greatest attribute is that the voltage across the switches is half the value of the input voltage. A prototype operating at 100 kHz, rated at 600 V input voltage, 1.5 kW output power, and 25 A output current, has been fabricated and successfully tested in the laboratory. The principle of operation, theoretical analysis, design procedure, and an example, along with experimental results, are presented. |

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.
