ALTERNATING VOLTAGE STABILISER

FIELD: electricity. ^ SUBSTANCE: alternating voltage stabiliser comprises transformer and comparator differing by the fact that it includes sinusoidal generator, balancing device, amplitude stabiliser, integrator, phase detector, output amplifier and threshold device. Input voltage is supplied to the first lead-out of the transformer secondary winding and the first lead-in of the phase detector with the lead-out of the latter being connected to the integrator lead-in. The integrator lead-out is connected to the lead-in of the sinusoidal generator with the lead-out of the latter being connected to the balancing device lead-in. The balancing device lead-out is connected to the lead-in of the amplitude stabiliser with the lead-out of the latter being connected to the first lead-in of the comparator and second lead-in of the phase detector. Output voltage is supplied from the second lead-out of the secondary transformer winding to the second lead-in of the comparator with the lead-out of the latter being connected to the first lead-in of the output amplifier and the lead-in of the threshold device. The threshold device lead-out is connected to the second lead-in of the output amplifier. First lead-out of the output amplifier is connected to the first lead-out of the transformer primary winding, second lead-out of the output amplifier is connected to the second lead-out of the transformer primary winding, third lead-out of the output amplifier is connected to the third lead-out of the transformer primary winding. ^ EFFECT: ensuring greater accuracy in upkeeping the output voltage. ^ 1 dwg
