Magnetic Voltage Source For Voltage Current Regulators

Drawing A shows at 10 a variable voltage reference source used to produce at terminals 12 a voltage for regulating the voltage applied to load 14 from an unregulated source, not shown.

A pair of phase locked oscillators (PLO's) 16 and 18 are differentially coupled by transformer 20 to provide a constant voltage source 21. This applies a constant reference voltage to bridge circuit 22 through one side of switch 23 and rectifier and filter circuits 24.

PLO 16 has variable impedance 27 which adjusts the differential output of transformer 20 and, hence, the voltage-at terminals 12. potentiometer 29 applies a portion of the load voltage to one leg of bridge 22. The resultant output of circuit 22 is applied to control windings 28c and 28d of PLO 28. This, coupled with PLO 30 through transformer 32, provides a differential amplifier with an output voltage at terminals 12 for regulating the voltage at load 14.

By connecting the DC windings 18c, 18d, 28e, 28f and 30c, 30d to a source of Idc through the other side of switch 23, and coupling the PLO's by transformers T1, T2, and T3, the correct oscillation phase of PLO's 18, 28 and 30 with respect to PLO 16 is insured.

Drawing B shows a current regulating reference source 40. This uses reference source 21 to apply an AC voltage to bridge circuit 42. This has connected to one leg the output of PLO 44. Its DC windings 44c and 44d are connected to be energized by the curre...
