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 ...

Gallium nitride has the advantage of high frequency characteristics. Currently, the gallium nitride fast charging frequency starting at exceeding 100KHz, even as high as 300KHz. As the power devices' switching frequency increases significantly, various parasitic parameters gradually affect the fast charging efficiency under high frequency conditions.How to eliminate the influence of parasitic para...

The planar transformer is special designed for low profile & low loss but high power application. Compared with traditional toroidal transformer, laminated core transformer, etc., the planar transformer can be through-hole mounted to the board, or can be integrated into PCB directly , thus the low-profile transformer that could handle a range of current values work. A PCB with traces...

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...

The planar core's successful development, a planar transformer (inductor) design was realized. Comparing to traditional transformer, the planar transformer (inductor) winding is a planar structure, have priority including: high current density, high efficiency, low leakage inductance, excellent heat conduction, low EMI radiation, small size, The pa...

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...

Nanocrystalline core, a soft magnetic core is a component used in electornic and electrical devices to channel and concentrate magnetic field.  The choice of core material and design depends on the specific requirements of the application, such as frequency range, current capacity, and efficiency. Take 1K107A and 1K107B as comparing: 1K107A has higher magnetic permeability at low frequencies,...
