Abstract
MAJOR PROBLEMS in devising reversible polarity direct current magnetic amplifiers are poor efficiency and large voltage regulation. Conventional reversible polarity circuits have a maximum theoretical efficiency of 50 per cent as compared to 100 per cent for the circuit under consideration. The increase in efficiency is accomplished by using switched transistors in conjunction with magnetic amplifiers. Previous applications of switched transistors have had magnetic amplifier gate windings in series with the transistors. Such circuits have the disadvantage of requiring the use of power magnetic amplifiers.
