What are the uses of high frequency transformers? What is the reason for the low number of turns
What is the use of high frequency transformer?
use:
1. To improve the conversion efficiency, use the power supply of a high-frequency transformer. Since the power tube works in an instant on-off state, that is, a state of continuous conversion when one is on and one off, we call it "switching power supply". The loss is about 30% lower than the traditional iron core transformer. Unfortunately, the failure rate is relatively high.
2. It can transform high-frequency pulses. The iron core of ordinary transformers does not have the high permeability of ferrite cores. can't do it
3. Improve the conversion efficiency, use the power supply of the high-frequency transformer, because the power tube works in an instant on-off state, that is, a state of continuous conversion when one is on and one off, so we call it "switching power supply". The loss is about 30% lower than the traditional iron core transformer. Unfortunately, the failure rate is relatively high. What can be learned from is the comparison of old-fashioned ballasts and electronic ballasts
Why is the number of turns in a high frequency transformer so small?
The transformer winding is an inductive device, and its inductance L is a proportional function of the number of turns when the magnetic core is fixed. When the magnetic core and winding of the transformer are fixed, the inductance is fixed.
The current in the inductor I=U/RL
Where RL is the winding inductive reactance = 2x3.14xPxL where P is the power supply frequency, that is to say, the higher the frequency, the greater the inductive reactance. When the frequency is high, very few windings will produce a large inductive reactance without short-circuiting, so It is said that the higher the frequency, the fewer turns will be.
The transformer winding is an inductive device, and its inductance L is a proportional function of the number of turns when the magnetic core is fixed. When the magnetic core and winding of the transformer are fixed, the inductance is fixed.
