New IEEE Standard - Superseded. This standard pertains to ferroresonant transformers used as regulators in electronic power supplies and in other equipment. Guides to application and test procedures are included.
This standard pertains to ferroresonant voltage regulators which operate at relatively constant frequencies and provide substantially constant output voltages in spite of relatively large changes of input voltage, and to controlled ferroresonant regulators which maintain substantially constant output voltages regardless of variations, within limits, of input voltage, temperature, frequency, and output load. Guides to application and test procedures are included. Provision is made for relating the characteristics of ferroresonant regulators to associated rectifiers and circuits. Definitions pertaining to ferroresonance and ferroresonant regulators which have not been found elsewhere are included with an appropriate discussion. This standard includes, but is not limited to the following types of ferroresonant regulators: (1) Series ferroresonant regulators (2) Series-parallel ferroresonant regulators (electrically connected) (3) Ferroresonant transformer regulators (magnetically coupled) (4) Controlled ferroresonant regulators
The purpose o f this standard is to provide a common ground of understanding between engineers involved in the design, manufacture, sale, and use of ferroresonant transformers. It pertains to ferroresonant transformers used as regulators in electronic power supplies and in other equipment where the inherent properties o f voltage regulation and current limiting are useful.
