Series-Connected Saturable Reactor with Control Source of Comparatively Low Impedance

The object of this analysis is to shed light onto the mechanics of magnetic-amplifier operation and to derive simple, and yet reasonably accurate, formulas. The analysis deals with the effects of various parameters, such as voltage, frequency, load resistance, and feedback. The various mathematical expressions are condensed into a nondimensional, normalized master graph which completely describes the steady-state operation of the magnetic amplifier under consideration. Speed of response and its relation to the gain are also investigated. The formulas and conclusions are verified by test data.
