Abstract | This paper presents a new family of DC/DC pulse-width-modulated (PWM) converters, featuring soft-commutation at zero-current (ZC) in the active switches. The new ZCS-PWM boost and new ZCS-PWM Zeta converters, both based on the new ZCS-PWM soft-commutation cell proposed, are used as examples to illustrate the operation of the new family of converters. This soft-commutation cell proposed is composed of two active switches (main and auxiliary transistors), two diodes, two small resonant inductors and one resonant capacitor. In this cell, the turn-on of the active switches occurs in zero-current (ZC) and they turn off in zero-current and zero-voltage (ZCZV). For the diodes, their turn-on processes occur in zero-voltage (ZV) and the reverse-recovery effects of them are eliminated. These characteristics makes this cell suitable for insulated-gate bipolar transistors (IGBTs). The family of DC/DC converters, generated based on this new soft-commutation cell, provides conditions to obtain naturally isolated converters, as an example: derived buck-boost, Sepic and Zeta converters. The principle of operation, the theoretical analysis, a design example for the new boost DC/DC converter and experimental results for a test unit with 1.6 kW output power, 400 V/sub dc/ output voltage, 220 V/sub dc/ input voltage, operating with 20 kHz switching frequency, are presented. Its measured efficiency is equal to 98.1% at rated load. Also presented is the principle of operation, the theoretical analysis and a design example for the new Zeta DC/DC step-down converter. |

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.
