Abstract :
THE BASIC self-saturating, bridge-connected magnetic amplifier is shown in Figure 1. There the voltages appearing in series with the control windings are labelled as ec, the control voltage, and eb, the other possible sources of voltage within the control circuit. eb arises most commonly from two sources; first, from the changes of voltage drop across control circuit resistance resulting from changes in the control current; and secondly, from voltage feedback connection with the output circuit.
