Description
A typical simple mag amp contains two identical coils, each having identical high permeability square loop magnetic cores and each wound with an identical winding not shared with the other coil. An alternating voltage source is connected to one end of these windings and a load is connected to the other end. The windings are either connected in series or in parallel such that the cores' magnetic flux generated by the alternating voltage are out of phase (in opposite directions). Alternating current (A.C.) will flow through these windings. Either a shared second winding is wound on both coils or each coil is wound with a second identical winding. In the latter case the windings are series connected such that a direct current (D.C.) flowing through these windings generate magnetic flux in the cores, which are in phase (in the same direction). These windings are connected to a variable D.C. current source (which might consist of series connected D.C. voltage source and a variable resistor). The D.C. winding(s) is (are) referred to as the control winding(s). Schematic representations of two typical mag amps are given in Figures 1 and 2 further below. The mag amps shown may also be referred to in literature as a type of saturable reactor. A mag amp may also be referred to in literature as a type of transductor.
