Common mode inductor Characteristics

Common mode inductor, saturable inductor and peak suppressor are all required small signal state, higher inductance is better .

On the basis of L=0.4 PI µ eN2Se/100 x I (µ h) in the formula:

µ e: effective permeability

S: effective cross-sectional area (cm2)

N: the winding turns L

I: average path length (CM)

Similarly, for the same size of the core, the effective permeability µ e higher and the inductance greater, and thus common mode inductors, saturable inductor and peak suppressor made by the amorphous and nanocrystalline alloy core has the following characteristics:

High effective permeability,

High inductance,

Small size

Straightening play stress is low, low loss

Less winding turns number, small distributed capacitance

High saturation magnetic induction and EMI noise effect

High Curie temp point, stable temperature performance (-50℃ ~ +130 ℃)

Good frequency characteristics

Application :

Switching Mode Power Supply

UPS uninterrupted power supply

Pulse welding equipment

Power converter

Wind power generator

Various transmission devices

Other single phase or three-phase power lines and common mode filters in various power supply

The working principle:

When the working current flow over the two opposite coil, there are two cancelled each other out field H1, H2. At this time ,working current is mainly affected by ohmic resistance of the coil and the neglected low leakage inductance under operating frequency . If there is an interference signal flow through the coil, the coil shows a high impedance, resulting in a strong damping effect to achieve the effect of attenuation interference signal.
