PFC Impacted by EMI Filter
Modern switch-mode power supplies use a combination of X- and Y-capacitors with inductors to filter common- and differential-mode EMI. The filter element sits in front of any active (or passive) power-factor–correction (PFC) circuit (Figure 1), so any distortion on the power factor (PF) imposed by the reactance of the EMI filter will …
