| Abstract | This work analyzes two solutions for ringing voltage problems occurring in the output voltage of a zero-voltage and zero-current switching phase-shifted pulsewidth modulation full-bridge DC-DC converter intended for automotive applications. An RCD snubber and an active snubber (thereafter called "modified flyback converter" since it includes a flyback converter to provide an additional power supply) are designed to reduce the ringing voltage caused by mainly the interaction among the transformer leakage inductance and circuit parasitic capacitances. This converter with the RCD snubber and the modified flyback converter has efficiencies of 91 % and 92 %, respectively, at 42-V 1-kW full load. The converter without any snubber has a lower efficiency of 88.7 %. Experimental and simulation results are shown to complement the theoretical analysis. |

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.
