Why does the winding turns of high-frequency transformers so small?
Transformer windings are inductive devices. When the magnetic core is fixed, its inductance L is proportional to the number of turns. When the magnetic core and winding are fixed, its inductance is fixed.
Current in inductance I=U/RL
Where RL is the inductance of the winding = 2×3.14xpXL, where P is the power frequency, that is to say, the higher the frequency is, the greater the inductive reactance will be, and When the frequency is high, few windings will also have a great inductive reactance and will not short circuit. So the higher the frequency is, the fewer turns will be.
