Silicon steel sheet is a ferrosilicon soft magnetic alloy with extremely low carbon content, general silicon content is 0.5-4.5%. The addition of silicon increases the resistivity and maximum permeability of iron, and reduces coercivity, core loss (iron loss), and magnetic aging. Silicon Steel mainly used to make cores for various transformers, motors and generators. The performance indicators of ...

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....

As usual, the transformer with a higher Q value, the better its quality and efficiency. Well, what should we do if the transformer's Q value is too low? What are the factors that lead to a low Q value? As we know: Q=XL/R=2 π fL/R, where XL is the inductance, R is the loss, and f is the operating frequency. The greater the loss, the smaller the Q value will be. For example, if there is a short circ...
