VARIABLE VOLTAGE REGULATOR Russian patent published in 2024 - IPC G05F1/30 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to conversion equipment, and can be used both for voltage regulation in electric networks, and for short-circuit currents limitation in electric networks. AC voltage regulator comprises: main transformer; booster transformer; two units of thyristor switches; phase-sensitive unit, made using two measuring transformers, two null elements, logic element "AND"; comparator unit, made using a null element, a logic element "OR", a logic element "AND"; two delay elements; measuring voltage transformer; auxiliary null element; auxiliary logic element "AND"; logic element "NOT"; three logic elements "AND"; auxiliary logic element "OR", two pulse shapers; protection unit made using an L-circuit, which serves as a single-turn winding of a magnetic conductor with an air gap, a magnetodiode, a variable resistor, a comparator, voltage divider, JK trigger, differentiating circuit, constant voltage source.

EFFECT: broader functional capabilities and higher reliability.
