Seeking tips on using J2121A High Power Line Injector to measure boost PFC inductors inductance with bias currents up to 20Apk and in the frequency range of 100kHz-500kHz. From what I have found there is not much published on using this particular injector in this manor and what needs to be done to make the measurements as accurate as possible. Also looking for information on if the current limit (20A) and voltage limits (400V) can be slightly exceeded without damage when measuring converter input & output impedances. As it is common for PFC output voltages / Isolation stage input voltages to be in the 390-450V range.
