Saturable-Core Reactor (Saturable Reactor) I. Description A saturable reactor in electrical engineering is a special form of inductor where the magnetic core can be deliberately saturated by a direct electric current in a control winding. Once saturated‚ the inductance of the saturable reactor drops dramatically. This decreases inductive reactance and allows increased flow of the AC current. II. Function/Operation Figure 1. This scheme controls the output voltage by varying the impedance
