High-frequency magnetic servo amplifier for air-borne control systems

THE ADVANTAGES of operating magnetic amplifiers at frequencies higher than the usual 60 and 400 cycles per second (cps) are improved transient response and reduced size and weight. These advantages are very important in the application of magnetic amplifiers to air-borne control systems. This paper presents results of the development of a high-frequency 4,700-cps magnetic servo amplifier used to drive a 400-cps servo motor for military aircraft applications.
