Abstract
Изобретение относитс к электротехнике и может быть использовано дл управлени тиристорами выпр мительных и ин- верторных установок. Цель изобретени - повышение надежности и продление ресурса электрооборудовани путем уменьшени веро тности возникновени субгармонических автоколебательных режимов, а также уменьшени уровн неканонических гармоник в спектре входных и выходных переменных статического преобразовател . Данное устройство содержит формирователь 1 кодов опорного сигнала, компаратор 2, логические элементы 2И 3 и 6, распределитель 4 импульсов, блок 5 синхронизации, генератор 7 случайного сигнала, инвертор 8 и логический узел 9. 1 з.п. ф-лы, 4 ил.The invention relates to electrical engineering and can be used to control thyristors of rectifying and inverting installations. The purpose of the invention is to increase the reliability and extend the electrical equipment life by reducing the likelihood of subharmonic self-oscillatory modes, as well as reducing the level of non-canonical harmonics in the spectrum of the input and output variables of the static converter. This device contains the shaper 1 reference signal codes, a comparator 2, logic elements 2I 3 and 6, a distributor of 4 pulses, a synchronization unit 5, a generator 7 of a random signal, an inverter 8 and a logic node 9. 1 c.p. f-ly, 4 ill.
