Abstract

1287133 Automatic voltage control WANLASS ELECTRIC CO 30 Oct 1969 [30 Oct 1968] 53222/69 Heading G3R [Also in Division H2] A voltage regulator comprises a parametric device having at least two windings, one of which is an input winding connected to a source of high frequency alternating voltage derived from an unregulated voltage supply and the other of which is an output winding coupled to a capacitor to form an energy storing tank circuit oscillating at a stable point and providing isolation of the output from the input such that regardless of the input, the output is determined by the tank circuit, the device operating such that the flux generated by either winding does not normally link the other winding, and the output winding being connected to an output circuit whose voltage variations are sensed to provide an error signal which is used to vary the frequency of the high frequency source to maintain the output circuit voltage at a desired value. The output voltage is DC obtained by rectifying and filtering the voltage of the output winding. In Fig.3 the parametric device is generally similar to that described in Specification No. 1206279 and comprises a variable inductor 53 and a capacitor 55 of which the inductor is generally similar to that described in Specification No. 1153901. A low frequency A.C. supply 48, 49 is rectified and filtered at 50 and passed to an inverter 51 (see Division H2) whose high frequency supply is fed to the input or control winding 52 of the inductor 53. The output from the energy storing tank circuit 54, 55, which is turned to the frequency of the inverter 51, is rectified and filtered to provide a D.C. voltage 57, 58, which is fed to a control amplifier and oscillator 59 providing an error signal in the form of a variable frequency pulse train. The latter controls the frequency of the inverter 51 through a variable frequency drive and delay logic 60, Fig. 5 (not shown) which ensures that short circuit conditions in the inverter 51, due to simultaneous conduction of its alternately conducting elements, cannot occur. In another embodiment, Fig. 2 (not shown) the output winding is tapped to provide the voltage for rectification and the inverter comprises silicon controlled rectifiers controlled by a conventional comparator circuit. A starting circuit is provided to reduce the output frequency of the inverter to initiate oscillations in the parametric device. Alternatively this may be accomplished by overdriving the input winding to cause transient mutual inductance between the two windings.
