An apparatus for controlling electrical characteristics in an alternating current system includes a first level of magnetic amplifiers which are responsive to a primary direct current control signal. The magnetic amplifiers provide secondary control signals in response to the primary control signal. The secondary control signals control a second level which includes a magnetic amplifier having gate windings to which the alternating current to be controlled is connected. Depending upon the nature of the primary control signal, the current magnitude or voltage magnitude of the alternating current can be controlled, both in relation to other alternating currents and in relation to a predetermined current or voltage magnitude.
