Abstract :
THIS ANALYSIS APPLIES to magnetic-amplifier circuits of the center-tap, bridge-type, or a-c variety. Such circuits are called amplistats, Magamps, transductors, self-saturated magnetic amplifiers, and so forth. Figure 1 shows the circuit diagram of the center-tap connection. The amplifiers under discussion are of the so-called low control-circuit impedance type. In order to reduce the complexity of the analysis, many simplifying assumptions are made. While these assumptions introduce inaccuracies in the equations, the latter still serve effectively in establishing first-order relations among the variables. A large part of the analysis is applicable to core materials whose dynamic B-H loop is not strictly rectangular, such as grain-oriented silicon steel.
