Transformer inductor core is a very important part of the transformer, the selection of appropriate inductor core can effectively improve the performance of the transformer, reduce energy consumption, increase service life. The selection principle of inductor core mainly includes the following points:
First of all, the choice of inductor core should be based on the transformer power and operating frequency to determine. Different power and frequency transformers have different requirements for the inductor core, generally speaking, the higher the power transformer needs to have a higher permeability and low loss inductor core.
Secondly, the material of the inductor core should be selected from materials with good magnetic properties, good thermal conductivity, small coefficient of thermal expansion and good stability. Common inductor core materials include silicon steel sheet, ferrite, AlNiFe alloy, etc. Select the appropriate material according to the specific requirements of the transformer.
Again, the shape of the inductor core needs to be determined according to the actual situation. Generally speaking, the inductor core of the transformer is selected from E-type, I-type, U-type and other shapes, and different shapes of inductor cores are suitable for different types of transformers, which can improve the efficiency of the transformer.
In addition, the size of the inductor core also needs to be determined according to the design requirements of the transformer. Too large or too small a size will affect the performance of the transformer, so it is necessary to determine the appropriate size according to the power, frequency and other parameters.
Overall, choosing the right inductor core is one of the key factors affecting the performance of the transformer. Only according to the actual needs of the transformer, choose the right material, shape and size of the inductor core, in order to ensure the normal operation of the transformer, improve efficiency and reduce energy consumption.
