| Abstract | In this study, polymer bonded soft magnetic materials (PBSMM) were investigated for the application as a magnetic core and electromagnetic shielding material in inductive devices for EMI filter applications. The nature of switch mode power converters makes them a potential source of EMI noise emission. EMI filters are generally necessary to ensure electromagnetic compatibility of converters to the other electronic equipment. Conventional discrete EMI filters usually comprise passive components with different volume and form factors. The manufacturing of conventional inductive components requires different processing and packaging technologies, of which many include cost intensive processing steps. Due to the parasitics of the discrete components and their interconnections the effective filter frequency range is limited. As a result discrete EMI filters are usually not integrable into an arbitrary formed volume and show relative high production costs. This study aims on solving this issue by the integration of inductive EMI filter components using polymer bonded soft magnetics. PBSMMs were produced using thermoplastic polyamide 6 matrix materials. The filler materials were chosen from the wide range of different soft magnetics. The magnetic properties were characterized using injection molded ring core test specimens and a computer controlled hysteresis recorder as well as an impedance analyzer. Inductive devices with PBSMM as magnetic core have great potentials in automotive applications that have to meet a high geometric flexibility and highest power densities. |

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.
