Description

TECHNICAL FIELD

[0002] PFC, means "power factor correction", power factor refers to the relationship between effective power and total power consumption (apparent power), that is, the ratio of effective power to total power consumption (apparent power). Basically, power factor can measure the degree of effective use of electric power, when the power factor value is larger, it represents that the power utilization rate is higher. PFC has two kinds, one is passive PFC (also called passive PFC), one is active PFC (also called active PFC). Passive PFC generally uses inductive compensation method to reduce the phase difference between the fundamental current and voltage of AC input to improve power factor, but the power factor of passive PFC is not very high; Active PFC is composed of inductance, capacitance and electronic components, small in size, and can achieve high power factor, but the cost is higher than that of passive PFC, when producing PFC items, PFC items need to be injection molded.
