摘要： An improved ferroresonant transformer for a ferroresonant power supply, such as may be used for charging storage batteries, is provided by placing damping means, such as a strip of non-magnetic metallic material in an air gap of such a transformer, thereby eliminating the need for a damping resistor in the circuit of the resonant winding of such a transformer, thereby decreasing the size, weight, and cooling requirements of such a transformer and power supply, and allowing a greater electrical energy efficiency to be obtained.

摘要： The primary winding of a saturable transformer is coupled to an alternating current source by a series tuned filter network. The transformer secondary winding is coupled to a load network by a second series filter tuned to the source frequency to block harmonics generated by the saturation limiting action of the transformer, which occurs below the normal voltage level of the source and regulates the output voltage supplied to the load within predetermined limits over the source operating voltage range. The first filter is tuned at a predetermined level above the source frequency to cooperate with the equivalent inductance of the unsaturated transformer and output network to hold the secondary output in phase with the input signal at a low levels of the source voltage. The first filter further cooperates with the reduced equivalent inductance of the saturated transformer and output network to change the effective frequency tuning to shift the phase of the secondary output with respect to the input signal at normal source voltage levels.

摘要： A parametric voltage regulator in which the inductance component of the resonant circuit of a parametric device is varied in response to changes in the output voltage, caused for example by changes in line frequency, to maintain the output voltage constant. The inductance is preferably changed by providing an external flux generator on the core of the parametric device to vary the reluctance of a part of the core, but can also be accomplished by the use of a separate inductor in the resonant circuit.

摘要： 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.

Preferably a secondary three-phase saturated compensating treble frequency reactor has a primary winding connected in star to symmetrical treble-frequency tapping points on the closed mesh, and a secondary winding connected to form a closed short-circuited mesh.
