The operation of magnetic amplifiers with various types of loads: Part II - Controlling the angle of firing. The transfer characteristics of amplifiers with low-control impedance

THE companion paper (part I)1 has supplied expressions for output currents and for currents in the load in terms of the angle of firing α taken as the independent variable. The treatment has been developed with reference to practical situations of magnetic amplifier circuitry, but substantially no need was felt for a close understanding of the phenomena taking place in the amplifier proper.
