The four-phase common mode choke is a four-terminal device, which founded by a nanocrystalline magnetic toroidal core as a common mode interference suppression device, four sets same size, same turns numbers coils wound symmetrically. When the common mode current flows, the magnetic flux in the magnetic ring superimposes each other, resulting in a considerable inductance, which has a suppressing e...

The Iron-base nanocrystalline  are composed of iron, silicon, boron and small amounts of copper, molybdenum, niobium, etc., of which copper and niobium are essential elements for living nanocrystalline structures. They were first fabricated into amorphous ribbons, which were then appropriately annealed to form a mixture of micro-crystalline and amorphous structures.Such material is not o...

The performance of nanocrystalline  core is determined by the  permeability of the strip used for the core and the size of the core (OD, ID, H) Derived from OD, ID, height H Cross sectional area of magnetic core：S = 1 / 2 (OD-ID) *H Magnetic circuit length L = π / 2 * (OD + ID) Due to the gap between the strip layers in the process of core winding, the effective cross-sectional area Se=f...

In switching power supplies, there are two common types of noise: common mode noise and differential mode noise. The noise with the same path as the input signal is called differential mode noise, while the noise from ground to output with the same phase is called common mode noise. Common mode inductance can suppress common mode noise and improve signal quality through filtering. As for power lin...
