The requirement of pulse transformer for iron core material is:
Oct 20, 2017

The requirement of pulse transformer for iron core material is:

(1)Bs value of high saturation magnetic induction;

(2) high pulse permeability can obtain enough excitation inductance with smaller core size;

High power unipolar pulse transformer requires that the core has a large magnetic induction intensity Delta B, using low remanence induction material; when additional DC bias is applied, the iron core has a high squareness ratio and a small coercive force Hc.

Small power pulse transformer requires high initial magnetic permeability of iron core;

Small loss.

The resistivity of the ferrite core is high, wide frequency range, low cost, low power pulse transformer in many applications, but the B and P are low temperature, poor stability, generally used on the top and down along the less demanding occasions.

(three) inductor cores

The iron core inductor is a basic component. In the circuit, the inductor has an impedance effect on the current change, and is widely used in electronic equipment. The main requirements for inductors have the following points:

For a long time, the inductance of inductors should keep the minimum rate with time;

The temperature coefficient of inductance should be kept within the allowable limit in the given range of operating temperature;

(3) the electric loss and magnetic loss of inductors are low;

Fourth, nonlinear bifurcation is small;

The price is low and the volume is small. Source: transmission and distribution equipment network

The inductance component has close relation with inductance quantity L, quality factor Q, iron core weight W, winding DC resistance R.

Inductance L AC current with inductive resistance value ZL: ZL = 2 pi fL frequency, the higher the F, the greater the reactance value of ZL
