ABSTRACT:
A ferroresonant voltage regulator circuit includes a non-saturating transformer, a linear reactor in series with the input, and a capacitor across the non-saturating transformer. Voltage sensing and referencing circuits are inserted in the output. A synchronous switch -- usually a saturable reactor, a magnetic amplifier, a triac or back-to-back SCR's -- is connected in shunt across at least a portion of the non-saturating transformer, and is controlled by its control coil in a manner such that the non-saturating transformer is loaded by the shunt loop at no-load conditions of the regulator. The control coil of the synchronous switch is connected in the voltage sensing and referencing circuits, and acts so that the amount of loading on the non-saturating transformer from the synchronous switch varies substantially inversely as the amount of loading because of the load on the voltage regulator circuit. A linear reactor may be series connected with the synchronous switch in the shunt loop. The non-saturating transformer has an air gap in its iron core so that it has a considerably more linear volt-ampere vs. flux density characteristic of the core and the air gap than that of a similarly rated and constructed saturating transformer.
