Power factor correction is abbreviated as PFC, which is mainly to improve the ratio of effective power to apparent power at the input end of a power supply. It is one of the common circuits in led dimmable power supplies.

Generally, the power factor of the input end of the model without PFC circuit is only 0.4~0.6, but with active PFC circuit, it can reach more than 0.95

Active power factor correction or active power factor correction (active PFC) refers to the power electronic system that can adjust the input current of the load and improve the power factor. Its main purpose is to make the input current close to the current of the pure resistive load and make it visible Power is equal to active power.

In an ideal state, its voltage and current phases are the same, and the reactive power it generates or consumes is 0, so that the power supply terminal can transfer energy to the load most efficiently.
