| Abstract | This paper addresses the effect of the isolating transformer parasitic capacitor in soft switched converter topologies that apply triangular inductor current. When a transformer is included in the circuit, it will not only add (leakage) inductance to the converter but will also add capacitance. This capacitance will cause a partial resonance behavior and therefore may alter the voltage transfer ratio of the converter. The objective of this study was to analyze the effect of this capacitance on the behavior of Triangular Current Shaped (TCS) soft-switched converters. The isolated TCS converter was analyzed and the theoretical results were verified by simulations and experimentally at a 1kW power level. The analysis show that the transformer's capacitance boosts the voltage gain of the converter, changes the shape of the inductor current and hence modifies the RMS value of the current. It was found though, that by proper design the RMS current (for same power level) may in fact be reduced and consequently, will result in lower conduction losses as compared to the case with no capacitor. |

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.
