Power Factor Correction (PFC) Circuit Basics Brent McDonald and Ben Lough AbstrAct From laptop adapters to power tools, any end equipment powered from the AC grid represents a complex load where the input current is not always in phase with the instantaneous line voltage. There's another one; PEFC = Prospective earth fault current When testing for PFC youu should test for both PSSC & PEFC; PSSC = between incoming phase & neutral. The active PFC methods are preferred for power supplies of over 100W. Ideally, electrical equipment should present a load that emulates a pure resistor, meaning that the reactive power would be zero. The correction method uses a low pass harmonic filter at the AC input with the capacitor and inductor forming a series resonance circuit. LM Photonics has more details about the power factor and PFC.

MEAN WELL Direct is an authorised UK distributor of MEAN WELL Power Supplies, PSU and Power Chargers one of the largest switching power supply manufacturers in the world. With power factor equal to 1 or as close as possible, there are lower losses and all power generated is utilized efficiently. What does PFC mean? Simply, it is a measure of how efficiently the load current is being converted into useful work output and more particularly is a good indicator of the effect of the load current on the efficiency of the supply system. Power factor correction tries to push the power factor of the electrical system such as the power supply towards 1, and even though it doesn’t reach this it gets to as close as 0.95 which is acceptable for most applications. Requires more filtering because of the high frequencies which can get into the line. However, due to the reactive components in a majority of circuits, there is always a power lag that leads to lower power factors.
