Special Design for China Switching Power Transformer Half Bridge for LED Lighting

Short Description:

high quality common mode filter inductor , also called filter inductor or Inductive Reactive Loads, Mainly used for filter application, Lighting LED drive and power supplies. It is a common mode interference suppression device with ferrite core. It consists of two coils of the same size and the same number of turns symmetrically wound on the same ferrite toroidal magnet.

On the core, a four-terminal device is formed, which has a suppressive effect on the large inductance of the common-mode signal, but has little effect on the small leakage inductance for the differential-mode signal.The principle is that the magnetic flux in the magnetic ring superimposes each other when the common mode current flows, which has a considerable inductance and suppresses the common mode current.

When the differential mode current flows through the two coils, the magnetic flux in the magnetic ring Passes cancel each other out, there is almost no inductance, so the differential mode current can pass without attenuation. Therefore, the common mode inductance can effectively suppress the common mode interference signal in the balanced line, but has no effect on the differential mode signal normally transmitted by the line.

The filter inductor is usually made of ferrite material, which can be easily combined with the through capacitor to form a composite filter. In the high performance filter, the wire wound inductor is also used.

With below information, we could help to customized the product:
