Abstract

The alternating-voltage stabilizer contains an autotransformer (1) with an increasing secondary winding (2), regulating elements and a control unit (19). The autotransformer additionally comprises a decreasing secondary winding (3), one end of which being connected to one end of the increasing secondary winding and to one end of the primary winding, the second ends of the secondary windings are connected to two fixed contacts (5, 5′) of the electromagnetic relay (7). In the capacity of regulating elements are used two degenerative-type constant-voltage stabilizers (10, 16), each of which comprises additionally two inversely connected diodes, one of which (9, 17) is connected between the collector and the transistor emitter, and the second (12, 14) - into the circuit of the stabilizer diode (11, 15), at the same time the two stabilizers are connected to the load (18) in series, and about each other - conversely. The medium mobile contact (6) of the relay is connected to the collector of the first stabilizer's transistor. The control unit comprises a bridge rectifier (21), into the output diagonal of which there is connected a null detector (22), coupled with the third secondary winding (4) of the autotransformer and with the power supply circuit (23) of the relay winding.
