Description
(З)УСТРОЙСТВО ДЛЯ УПРАВЛЕНИЯ ТИРИСТОРАМИ ТРЕХФАЗНОГО ИМПУЛЬСНОГО ИСТОЧНИКА НАПРЯЖЕНИЯ(W) DEVICE TO CONTROL THIRISTORS OF THREE-PHASE PULSE SOURCE OF VOLTAGE
; Изобретение относитс к преобразовательной технике и может быть использовано дл управлени тиристорами трехфазных импульсных источников напр жени , примен емых в установках электрохимической обработки и в других устройствах.; The invention relates to converter technology and can be used to control thyristors of three-phase pulsed voltage sources used in electrochemical processing plants and other devices.
По основному авт. св. ff 7 1385 известно устройство дл управлени тиристорами трехфазного импульсного истбчника напр жени , содержащее диоДы и в каж,цой фазе блок синхрони )зации, выход которого через разделительный диод включен в цепь шунтирующего электронного ключа, и выходной формирователь импульсов, включающий в себ чейку блока магнитной пам ти, причем блок синхронизации выполнен в виде генератора на однопереходном транзисторе с (|)азосдвигающей RC-цепью в цепи базы, а блок магнитной пам ти выполнен в виде трехфазного кольцевого регистра сдвига на феррит-транзисторных чейках, вхолAccording to the main author. St. ff 7 1385 a device is known for controlling the thyristors of a three-phase pulsed voltage source, which contains diodes and, in each phase, a synchronization unit, the output of which through the separation diode is connected to the shunt electronic key circuit, and the output driver of the pulses, which includes a cell memory, moreover, the synchronization unit is designed as a generator on a single junction transistor (|) with an azo-shifting RC circuit in the base circuit, and the magnetic memory unit is designed as a three-phase ring shift register rt transistor cells
ды которых подключены через диоды к выходам блоков синхронизации соответствующей фазы which holes are connected via diodes to the outputs of synchronization blocks of the corresponding phase
Недостатком известного устройства вл етс невысока надежность, обусловленна невозможностью получени на нагрузке импульсов с крутым задним фронтом и регулируемой длительностью без изменени амплитуды.A disadvantage of the known device is the low reliability due to the impossibility of obtaining pulses on a load with a steep falling edge and adjustable duration without varying the amplitude.
