Abstract:

Ferrites are frequently employed as an auxiliary component in high voltage pulse circuits. The ferrite has a twofold purpose. One is to improve the pulse rise time in a low inductance circuit where the rise time is limited by the resistive fall time of the switch, typically a thyratron or an SCR. The other purpose is to reduce dissipation in the switch. The ferrite accomplishes these goals by behaving as a nonlinear inductor, or saturable reactor. At about the same time that the switch becomes fully conducting, the ferrite inductance rapidly saturates, i.e., the pulse permeability quickly changes from a large value to a relatively small one.
