What are the influencing factors of high-current three-phase common-mode inductance?
Editor: Gujing Electronics.
As a very important electronic component, the inductance of high-current three-phase common-mode inductor is an important reference factor for selection. There are often questions about the inductance of inductance, and in this article we will briefly take a look at what factors will affect the inductance of high-current three-phase common-mode inductors.
1. The influence of the number of turns wound by the coil on the inductance: Someone asked whether the inductance coil will be wound less than one turn will affect the use, of course. To put it simply, the more turns the coil is wound, the greater the inductance of the high-current three-phase common-mode inductor. Of course, when choosing an inductor, it is also necessary to select the corresponding inductance according to the actual application requirements, and do not only pursue a large inductance.
2. The influence of working frequency on inductance: simply put, the inductance of the inductance will change with the change of working frequency. In the low frequency band, the inductance of the common mode inductor is relatively large;In the high frequency band, the inductance is smaller.
3. The influence of temperature on the inductance: the temperature will also have a certain impact on the inductance of the high-current three-phase common-mode inductor. As the temperature increases, the permeability of the core material decreases, resulting in a decrease in inductance.
4. The influence of inductance materials on inductance: This point is easy to be ignored, and the materials used in high-current three-phase common mode inductors will also have an impact on inductance. Therefore, sometimes we can improve the sensitivity by adjusting the production materials.
The above are some of the factors that may affect the inductance of high-current three-phase common-mode inductors, what other factors do you know?Feel free to chat with us**.
