Characterization of a Hard-Switching Motor Controller for EMC considerations

摘要

The overall objective of this research is to characterize Power Electronic Building Blocks (PEBBs) for application of electromagnetic compatibility (EMC) in existing and advanced shipboard electric power systems. Both emissions and susceptibility levels will be studied, first for radiated EMI and later for conducted EMI. The EMI suppression techniques in large and small high-density power electronic modules will be developed. This document presents the results of the initial efforts toward the overall research objective. These initial efforts include setting up the EMI measurement facilities, developing EMI measurement techniques, and performing radiated emission tests on a motor controller, which is a hard-switching device.
