Abstract :
Past practice in a-c controlled magnetic amplifiers has required a relatively large resistance in series with the control windings to limit the circulating currents caused by the induced emf (electromotive forces) of the control windings. This resistor necessarily wastes signal power, and the realizable gain is much less than could be obtained from a d-c controlled amplifier.
