SELF-SATURATING MAGNETIC AMPLIFIERS WITH FREQUENCY DEPENDENT NETWORKS

Abstract

A variety of two-core full-wave self-saturating magnetic amplifiers in conjunction with either frequency dependent loads or feedbacks are studied, emphasizing the bridge-type amplifier with resistive-capacitive load and conventional feedbacks and the same amplifier with resistive load and frequency sensitive feedback networks. Steady-state gain expressions are derived for square-wave and sinusoidal gate supply voltages. The possible subharmonic response of the amplifier with resistive - capacitive load is explained and conditions for its avoidance are derived. The transient behavior and stability of the various second-order circuits has been studied using a difference-equation approach, and the results are interpreted in terms of an equivalent modular differential equation of the second-order. Extensions to sinusoidal supply are considered and the limitations of the squarewave analysis for such situations are discussed. Extensive checks of overall system behavior confirm the validity of the analyses. (Author)
