This talk will introduce the Compliance Feasibility Study (CFS) tool, part of the EMC solution D4Compliance developed by ITG Electronics Inc. and Power Electronics and Electrical Power Research Lab (PEEPRL), supervised by Dr. Shuo Wang at the University of Florida. Using CFS, users can estimate conducted EMI test results for converters under simple experimental conditions and receive EMI filter design recommendations. This avoids high costs of dedicated test facilities and solves filter design iteration difficulties.
