Hello,
Many of the active PFC IC datasheets show a DM Capacitor (often indicated by C_in/C_filter) following the bridge rectifier to filter out the high frequency noise. How is this capacitor value to be selected? And what will happen if one goes for a larger value of Cin? (usually small values around 1uF are used)
Example Datasheet
Regards
