DEVICE OF CURRENT STABILIZATION OF VOLTAGE SOURCE Russian patent published in 2004 - IPC

FIELD: electrical engineering, applicable for provision of constant-error behavior of the external characteristic of an AC voltage source in reactive current in various automatic voltage control systems.

SUBSTANCE: the device has coils inductive-coupled to the load current conductors of the voltage source, and regulating elements connected to the mentioned coils, these coils and the regulating elements form part of the electric circuits connected between the first and second terminals of the device, connected respectively to the output terminals of the mentioned voltage source and the output terminals of the voltage regulator of this voltage source. The coils of differentiating induction current converters are used as coils, and a switch, whose number of input terminals of the poles equals the number of the mentioned coils is used as regulating elements.

EFFECT: reduced total number of elements of the device, current transformers elements inductive-coupled to the load current conductors of the voltage source are substituted for by differentiating current converters, having a mass lower by tens and hundreds times.
