Power Factor Correction (PFC) Inductor
“PFC” is the abbreviation of “Power Factor Correction”, refers to the adjustment via circuit structure, generally improving the power factor in the circuit, reducing reactive power in the circuit, and improving the effectiveness of power conversion. Simply put, using PFC circuits can save more power. PFC circuits are used for power modules in power products or electronic devices.

Boost Inductor (Boosting Voltage Converter)
Boost inductor is an electronic component whose main function is to increase the input voltage to the desired output voltage. It is composed of a coil and a magnetic core. When current passes through the coil, the magnetic core generates a magnetic field, which causes a change in the current in the inductor, thereby generating voltage.

Common Mode Inductor or Choke
If a pair of coils in the same direction are wound around a magnetic ring made out of a certain magnetic material, when alternating current passes through, magnetic flux is generated in the coil due to electromagnetic induction.

Buck Inductor (Step-down Voltage Converter)
1. Good dynamic characteristics. Because the internal inductance is small, the electromagnetic inertia is small, and the response speed is fast (the switching speed is on the order of 10ms). It can meet the short-circuit current growth rate when used for flat characteristic power supply, and it is not easy to produce excessive short-circuit current impact when used for down characteristic power supply. The output reactor is not only used for filtering. It also has the function of improving dynamic characteristics.
