Power factor correction – What is it? Why is it

Power factor correction (PFC) aims to improve power factor, and therefore power quality. It reduces the load on the electrical distribution system. This improves the power factor from the point where the reactive power source is connected, preventing the unnecessary circulation of current in the network.

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 alter even a perfectly corrected voltage
