| Abstract | This paper compares and suppresses the conducted Electromagnetic Interference (EMI) in Silicon Carbide (SiC) JFET and IGBT based motor drive systems. Two inverter prototypes - with SiC JFETs and Si IGBTs as the transistors are built using the same circuit layout and investigated accordingly. The comparisons start from the transient level of the inverter tested under clamped inductive switching conditions by using of a single inverter leg to the system level conditions of all three phases of each of the inverter drives are functioning. The conducted EMI comparisons include with no filter and with conventional CM filters. To identify the exhibited different filtering performance with the identical filters, two inverters are tested in the CM mode. This allows for the identification and analysis of their maximized CM and DM wave shape differences. The comparisons show that the high frequency noise level of SiC JFET drive under filtered condition is much higher than that of the IGBT's. Therefore, two methods of inserting ferrite beads at different current paths are proposed to mitigate the increased EMI. Respectively, the middle and high frequency noise of SiC JFET drive system are effectively suppressed to comply with the standard of IEC61800-3: C2. |

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.
