ABSTRACT:
Power conditioning apparatus exhibiting enhanced stability with respect to lagging phase angle conditions incurred in conjunction with load derived transients. The apparatus employs a synthesizer network structured having a regulator which is fashioned as a non-linear saturable transformer in parallel with a capacitor bank and which is supplied from a utility line source through input inductors. The saturable transformer components and associated capacitors form a ferroresonant circuit wherein the reactive components operate beyond the knee of a conventional magnetization curve. To develop the stiffness to suddenly lagging phase angle otherwise encountered with such synthesizers, a induction or synchronous motor is employed at the output of the regulators which operates in essentially no load fashion to create a stable output in the presence of load transient phenomena. An odd harmonic trap arrangement is provided to assure stability under severe operational conditions such as single phasing.
