Design considerations of the half-wave bridge magnetic amplifier

摘要

AN improved magnetic servo amplifier utilizing half-wave bridges in cascade has been extensively used in instrument-type servos designed at the U.S. Naval Ordnance Laboratory. The speed of response inherent in a magnetic amplifier of this type has made possible the application of conventional compensation and stabilization techniques.1 The result is dynamic servo performance characteristics far exceeding those of previous magnetic-amplifier servo systems employing magnetic amplifiers using full-wave circuitry.
