Changes in the EMC generic standards resulting from EFT/BURST attenuation capabilities of AC/DC power supplies

The paper presents test-setup and results of technical experiments carried out in order to demonstrate ambiguities in the EMC generic immunity test standards of IEC 61000-6-x series. These ambiguities result from application of undefined type of AC/DC power supply during Electrical Fast Transient / BURST immunity test. Authors showed that such approach may cause different test results and proposed relevant changes in the standards.
