| Abstract | In a vehicle, radiational noise generated by the common-mode current in an inverter system is the cause of electromagnetic problems of in-vehicle radio antennas. This paper proposes a new method ”Z-matched ACC” for suppressing the common-mode current at AM band. With this method, the freewheel current, which reduces the common-mode current suppression effect at AM band in conventional voltage-cancellation ACC, does not flow by setting the phase of the Z-matched circuit equal to that of the motor common line. Therefore, the Z-matched ACC can suppress the common-mode current at AM band. The suppression effect of the Z-matched ACC is superior to the conventional ACC from 100 kHz to 10MHz. In addition, the Z-matched ACC can reduce the size of the common-mode transformer over that for the conventional ACC by reducing the ET product applied to the common-mode transformer. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
