The relationship between inductance, turns, line diameter and air gap of high frequency transformer

1) According to the inductance calculation formula, AL=L/N2, the inductance is proportional to the square of the number of turns, and has nothing to do with the number of turns per volt of the high-frequency transformer. That is, the more turns, the greater the inductance. The smaller the number of turns, the smaller the inductance. The number of turns per volt of the transformer is related to the size and quality of the magnetic core, and the amount of inductance per turn is also related to the size and quality of the magnetic core, and the amount of inductance per turn of the transformer with more turns per volt is small. If the magnetic core is unchanged, the high-frequency transformer custom manufacturer increases the number of winding turns, which can provide greater inductance and more abundant electric energy.

2) The relationship between inductance and wire diameter is basically no big difference in the case of a small number of turns, but it is obvious if the number of turns is a lot, for example: I-type inductors, the closer the coil as a whole to the axis, the greater the inductance because the magnetic field line is not easy to dissipate, for example, two inductors of the same number of turns a very neatly wound a very messy so a neat inductance must be large, the line diameter a thick a thin so fine inductance must be large the axis a thick a thin so fine inductance must be large is this reason.

3) Air gap, wire diameter and inductance are inversely proportional 1. The same winding the same wire diameter, the same number of turns under the condition, the deeper the air gap, the smaller the inductance. The deeper the air gap in the core, the lower the permeability and the smaller the inductance. 2. Under the condition of the same number of turns and the same air gap depth, the smaller the wire diameter, the greater the inductance.
