Abstract :
Synopsis. A half-wave voltage-reset magnetic amplifier with a switching transistor in the control circuit is used as a core tester. Families of magnetizing current versus the magnitude of induced voltage with reset flux as a parameter are recorded. A graphical construction similar to the conventional one in the design of electronic amplifiers can yield the core behavior when operating in a 2-core magnetic amplifier, regardless of the magnitude of the control resistance.
