Magnetic amplifier circuits ?? A classification of half-wave and full-wave nonreversible and reversible self-saturating circuits

This article attempts to give an orderly, critical classification of a wide variety of self-saturating single-phase series-control magnetic-amplifier output circuits. It the article is successful, it will be clear that a confusing multitude of circuits appearing in the literature may be fitted into a very simple scheme. The relative merit of various alternative circuits for accomplishing different types of output will also become apparent.
