Изобретение относитс к электротехнике и может быть применено в устройствах управлени вентильными преобразовател ми .The invention relates to electrical engineering and can be applied to control devices for valve converters.
Известно устройство дл управлени вентильным преобразователем, содержащее генераторы пилообразного напр жени , элемент гальванической разв зки , формирователь импульсов 1.A device for controlling a valve converter is known, comprising a sawtooth generator, an electrical isolation element, a pulse shaper 1.
Недостатком этого устройства в- ,р л етс низка надежность, обусловленна узким диапазоном регулировани и инерционностью.A disadvantage of this device is that the reliability is low due to the narrow range of regulation and inertia.
Наиболее близким к изобретению по технической сущности вл етс уст-,5 ройство дл управлени вентильными преобразовател ми, содержащее генератор синхронизирующих импульсов, вход которого предназначен дл подключени к напр жению сети, Лормиро- 20 ватель выходных импульсов и фазосдвигпющую чейку с nepBbifA и вторым входом, предназначенным дл подключени к источнику напр жени 2.The closest to the invention in its technical essence is a device for controlling valve converters, comprising a clock pulse generator, the input of which is intended to be connected to the mains voltage, an output pulse suppressor and a phase shifting cell with nepBbifA and a second input, designed to be connected to a voltage source 2.
Недостатком известного устройства вл етс низка надежность, обусловленна слабой помехозащищенностью от помех частоты, не кратной частоте пульсаций выпр мленного напр жени .A disadvantage of the known device is low reliability due to low noise immunity from frequency interference that is not a multiple of the ripple frequency of the rectified voltage.
Цель изобретени - повышение надежности управлени путем защиты системы управлени от помех частоты, не кратной частоте пульсаций выпр мленного напр жени .The purpose of the invention is to increase the reliability of control by protecting the control system from frequency interference that is not a multiple of the ripple frequency of the rectified voltage.
Поставленна цель достигаетс тем, что известное устройство снабжено элементом ИЛИ и двухвходовым коммутатором , причем генератор синхронизирующих импульсов подключен к одному входу коммутатора и через один вход элемента ИЛИ подключен к Оазосдвигающей чейке, выход которого подключен к другому входу коммутатора, один выход коммутатора подключен к входу формировател выходных импульсов, а другой - к другому входу элемента ИЛИ.The goal is achieved by the fact that the known device is equipped with an OR element and a two-input switch, the clock generator is connected to one switch input and through one input of the OR element is connected to the Oasdix cell, the output of which is connected to another switch input, one switch output is connected to the input of the switch output pulses, and the other to another input of the element OR.
