As we know, the inductance value will influence inductors application, today let’s talk about how to select an inductors based on inductance value. During the inductance is almost not stable during the entire working period of the components,  understand the effective value scope is particularly important. Thus, you should know your power circuit's inductance scope clearly. For inductors in p...

With the development of the global economy, the importance of effectively utilizing energy, reducing environmental pollution and preventing environmental emergencies has become increasingly prominent. Protecting the environment is not only related to the living environment of all human beings, but also affects the development of the global economy. 7 countries announce ban on sale of petrol and di...

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....

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...
