Working principle and main use of high frequency transformer

First, the working principle of high frequency transformer:

Transformer is the conversion of AC voltage, current and impedance devices, when the primary coil through AC current, the iron core (or magnetic core) will generate AC flux, so that the secondary coil induced voltage (or current). A transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the rest is called the secondary coil.

Two, the use of high-frequency transformer:

1, can be on the high frequency pulse transformer, ordinary transformer core does not have the high permeability of ferrite core, can not do this.

2, improve the conversion efficiency, the use of high-frequency transformer power supply, because the power supply tube work in the instantaneous on-cut-off state, that is, a switch state, so we call it "switching power supply". The loss is about 30% lower than the traditional core transformer. Unfortunately, the failure rate is relatively high. One thing that can be used for reference is the comparison between old ballasts and electronic ballasts.
