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...

PFC inductors are widely used in switching power supplies because they improve power factor, power efficiency, electromagnetic interference, and greatly enhance circuit stability.   The working principle of PFC inductor is that when the current passes through it, the magnetic field generated will reduce the rate of change of the current, thereby reducing high-order harmonics in the circuit, s...

For the transformer and inductors, we always test Q value. While, what's Q value?What factors are it related to? Q value, as know as  quality factor, its basic meaning refers to the ratio of inductance to loss pressented by a transformer (inductor) when operating at a certain frequency of AC voltage, it is an important parameter for measuring the transformers and inductors. The higher Q value...

To achieve good performance, when making the magnetic ring inductors, it's crucial to follow standard process design specifications. In terms of design we should notice: 1. To ensure a stable inductance, we should avoid use 15K high conductivity magnetic cores. 2. For amorphous nanocrystalline cores, request plastic case, thus core damage of external forces could be reduced during core winding. 3....
