Introduction
PFC inductor is the core component of PFC circuit, which was used more in UPS power supply in the early days, and later with the emergence of some mandatory certifications (such as CCC), PFC inductors rose in the field of low-power power supplies.
PFC circuits are further divided into passive PFC circuits and active PFC circuits. Whether it is a passive PFC circuit or an active PFC circuit, the PFC inductor must be involved.
Applications
Iron-silicon-aluminum PFC inductors can be used in power supplies, uninterruptible power supplies (UPS) and various household appliance control boards.
Amorphous PFC inductors can be used in frequency conversion power supply, UPS, switching power supply, frequency converter, industrial power supply, communication power supply, etc.
Product features
Common PFC inductors include iron-silicon-aluminum PFC inductors and amorphous PFC inductors. Ferrosilicon aluminum PFC inductor core is made of iron-silicon aluminum material, its Curie temperature is above 410 degrees, the working temperature range is -50~+200 degrees, and it has the characteristics of good current superposition performance, low iron loss and negative temperature coefficient. Amorphous PFC inductor is made of iron-based amorphous strip, iron core opening, with excellent frequency characteristics and stability, good constant inductance characteristics and DC bias resistance, and low loss.
