Abstract :
THE purpose of this paper is to present some approximate expressions relating the factors that govern the self-excitation in magnetic amplifiers. Possibilities are shown of a compensation of diversities of rectifier characteristics so as to obtain uniform steady-state performance, simply by readjustments of feedback turns, without changing any other factors of design or operation. Moreover, the effects of controlled or uncontrolled (drifting) variations of feedback circuit parameters are examined in terms of resulting current gains.
