AC VOLTAGE STABILISER Russian patent published in 2013 - IPC G05F1/00 

FIELD: electricity.

SUBSTANCE: in an AC voltage stabiliser, comprising a control element of discrete action, connected between input and output leads of the stabiliser, a reversible counter connected with its outlets to control inlets of the control element of discrete action, a rectifier, the inlet of which is connected with outlet leads, a comparator by an inverting inlet connected to the rectifier outlet, and by a non-inverting inlet - to a source of reference voltage, a shaper of sync pulses, connected with its inlet to the inlet lead of the stabiliser, a generator of clock pulses, the first and second conjunctors, there is the first and second counters introduced, the first inlets of which are connected with outlets of the first and second conjunctors, and the second inlets - with the outlet of the sync pulses shaper, a logical device, to the second and third inlets of which there are outlets of the first and second counters connected, and the first inlet - to the outlet of the sync pulses shaper, an inverter with its inlet connected to the outlet of a comparator, and with its outlet - to the second inlet of the second conjunctor, besides, the second inlet of the first conjunctor is connected to the inlet of the inverter.

EFFECT: reduced error of stabilisation.
