Description

I

Pulse transformers are related to high voltage pulsed technology and are used in pulsed power supply systems for charged particle sources, high frequency generators, which include magnetrons or klystrons.

Pulse transformers are known in which magnetised ferrite inserts are used to simplify the demagnetization system of the core.

The disadvantage of such transformers is that they cannot be used when working with large values of induction, since it is possible to magnetise the liner, and as a result, deterioration of the operation of the pulse transformer.

In the proposed transformer, in order to eliminate the noted deficiency, i.e., excluding the degaussing of the liner, the cross section of the ferrite liner is chosen to be much larger than the cross section of the core, and the core plates adjacent to it are installed with a gap relative to each other, and in order to eliminate local areas The gaps between the core plates adjacent to it are magnetically padded.

The drawing shows the structure of a pulse transformer.

The core 1 of the pulse transformer is assembled from plates 2 and assembled from two halves. On one of the cores are wound primary and secondary windings 3. Between the halves

The second core is inserted magnetized ferrite liner 4 of a hard magnetic material. Between the core plates directly at the magnetized liner, gaskets 5 are laid on both sides of it, which

can be made of magnet and soft material.

When a pulse transformer is in operation, a magnetized ferrite insert of magnetically hard material creates in the core

magnetic flux. The polarity of the pulse or the direction of winding of the primary winding is chosen such that when a voltage pulse is applied to it, a non-magnetic field of the core occurs.

The optimal parameters of the pulse transformer and the minimum dimensions are possible if the core's magnetization reversal is close to saturation.
