Prediction of System-Level Emissions Performance via Equipment Shelf Primary Power Frequency Response Characteristics

This paper experimentally demonstrates that the behavior of the Primary Power Bus extended over the components of the system Equipment Shelf is a crucial predictor of the system's EMC performance. In particular, the Conducted and Radiated Emissions characterisrtics of the system can be predicted before the system is fully assembled. and long before System-Level formal compliance testing. The frequency pass-bands and resonances of the Primary Power Bus are identified and these outcomes are closely correlated with independently obtained Conducted and Radiated Emissions spectra for the populated system Equipment Shelf.
