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...
