| Abstract | General switching converter such as the simple high-side switching circuit inherently has unbalanced characteristics of impedance of transmission path, voltage at dc source and load terminals with respect to the frame ground. These unbalanced characteristic effects are the cause of unbalanced voltages at both dc source and load terminals. These unbalanced voltages will produce common-mode noise flowing through frame ground to the LISN during the active switch turn-off and on. This paper presents the analytical and experimental consideration of common-mode noise generation due to the unbalanced effect. The mechanism of common-mode noise generation due to unbalanced effect can be explained by equivalent circuit in both turn-off and turn-on time of the active switch. For common-mode noise reduction, the method for balancing the switching converter is also presented. Common-mode noise generated due to the effect of circuit imbalance is clarified by the experimental results. The balanced switching converter can greatly reduce the common-mode noise is also confirmed by the experimental results. |

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.
