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

100 kHz carrier frequency is a matter of conducted RF interferences. RF emissions aren't covered by IEC 61000-3-2. They are specified in EMC standards like CISPR-22 and IEC 61000-4-x.
