Determination of Steady-State Performance of Self-Saturating Magnetic Amplifiers

The performance of the half-wave circuit under the conditions of high external control-circuit impedance and no rectifier leakage is taken as the basis for the steady-state analysis of the self-saturating magnetic amplifiers. Transfer curves for the basic circuit are determined by a combination of idealized and no-load methods, each applied in the appropriate region of operation, and the results extended to the full-wave and doubler circuits. Rectifier leakage and control-circuit impedance effects are computed for each type of circuit. Transfer curves for all three circuits under practical operating conditions are obtained by correcting the basic curves for these effects. Satisfactory results are obtained on test amplifiers containing orthonik and hypersil cores.
