What is the Q value that affects the inductance of the magnetic ring?

The inductance Q value refers to the main parameter to measure the magnetic ring inductance. It refers to the ratio of the inductance to the equivalent loss resistance when the magnetic ring inductor works under the AC voltage of a certain frequency. The higher the Q value of the magnetic ring inductor, the smaller the loss and the higher the efficiency. The quality factor of magnetic ring inductance is related to the DC resistance of the coil wire, the dielectric loss of the coil frame and the loss caused by the core and shield.

Know the relevant factors related to the Q value, but how can we improve the quality factor in the design?

With regard to the relationship between magnetic loss and Q value, the design requirements of power supply are becoming more and more stringent, which requires us to carefully analyze and calculate each problem point. generally speaking, the calculation of magnetic loss is simply based on the volume of the magnetic core and the related loss curve, but in practical work, different winding methods of the same magnetic core have different tightness with the same winding mode of the same magnetic core. However, it brings different temperature rise gap and so on, but the magnetic loss is rarely mentioned in view of the relationship between the magnetic loss and the Q value. It is simply believed that the higher the Q value is, the smaller the magnetic loss is, but what factors the Q value is related to are less mentioned in practice. A
