Abstract :
The purpose of this paper is to describe a ¿power¿ method of measuring the useful, torque-producing component of the a-c output voltage from magnetic amplifiers used in applications wherein the output phase angle is important, and wherein the ideal phase angle, with respect to the amplifier´s excitation, is either zero degree or 90 degrees. Typical of such applications is a single-phase amplifier used to drive one phase of a 2-phase servo motor.
