<p>A three-path parametric regulating and filtering transformer having an adjustable output voltage. The regulating transformer includes a magnetic core having input, output and saturable regions, an input winding disposed about the input region, an output winding disposed about the output region, and a capacitor connected to the output winding to provide a tank circuit. In one embodiment, a magnetic element is disposed to influence the magnitude of the voltage across the output winding, with the position of the magnetic element, relative to the output winding, being adjustable. In another embodiment, the output region of the magnetic core is divided into two spaced portions, the output winding is disposed about both portions, and electrical control coils are disposed about each portion and connected in opposition. A unidirectional control current is passed through the control coils, with the magnitude of the unidirectional current controlling the voltage across the output winding.</p> |
