EMI Measurement Methodology
There are two methods of measurement for input conducted EMI: voltage measurements and current measurements. The
voltage data presented uses a 50S LISN (Line Impedance Stabilization Network) and measures the input voltage spectrum
from each input line of the converter to ground, using FCC and CISPR measurement techniques. The current data uses a
10 microfarad capacitor from each input line to ground, and measures the current in both lines simultaneously using the
measurement technique defined in section 3.4.5, part B3 of the Bellcore document GR-1089-CORE. In each case, there was
no external input filter. There was only an appropriate value capacitor across the input lines. The case of the unit under test
was grounded to the reference ground plane, as was the output common of the unit. All spectra presented were taken with
production grade modules, operating from 48 VDC at the full-rated output load current.
