Hi guys,
I'm in the middle of designing of an input filter for a power supply with an active PFC circuit. The power supply needs to comply with IEC 61000-3-2 for conducted emissions. I'm reading through the standard, but I'm having difficulties finding anything on the high frequency parts.
The maximum harmonic limited is the 40-th which at 60Hz makes 2.4kHz. But what about 100kHz, which is the frequency of PFC switching? What are the limitations for that? :-?
Regards,
Mercury
