Abstract :
ONE OF THE major difficulties in obtaining high performance from a magnetic amplifier servo system has been the slow speed of response of the magnetic amplifier. Although the magnetic amplifier is a carrier-type system and as such has a minimum response time per stage of one cycle of the supply or carrier frequency, this response is usually not obtained in conventional full-wave circuitry. A major factor contributing to the slow speed of response in such circuits is the inductance-resistance time constant in the control circuit.
