Description
противлени резистора 2. Сдвигаемое по фазе наир жение со вторичной обмотки 5 постулает на формирователь вспомогательных импульсов управлени маломощными тиристорами 15, 16. При достижеви-и уровн напр жени на стабилитроне 7, достаточного дл отпирани динистора 8, лоследний отпираетс , и на вторичных обмотках импульсного трансформатора 14 по вл ютс короткие импульсы, открывающее тиристоры 15, 16, которые подключают напр жение со вторичных обмоток 17 и 18 траисфо1рмато;ра 4 к управл ющим электродго силовых тиристоров 19, 20, причем фаза напр жени , снимаемого с обмоток 17 и 18, сдвигаетс так же, как и фаза вспомогательных импульсов управлени . Таким образом, на управл ющие электроды силовых тиристоров 19, 20 поступают отпирающие импульсы, длительность которых посто нна во всем диапазоне изменени сопротивлени резистора 2. resistor 2. Phase-shifting from the secondary winding 5 puts on the driver of auxiliary control pulses of low-power thyristors 15, 16. When the voltage on Zener diode 7 is sufficient for unlocking the distor 8, the last one is unlocked and on the secondary windings of the pulse Transformer 14: short pulses appear, opening thyristors 15, 16, which connect the voltage from the secondary windings 17 and 18 of the transistor; pa 4 to the control electrodes of the thyristors 19, 20, and the phase voltage The power removed from windings 17 and 18 is shifted in the same way as the phase of the auxiliary control pulses. Thus, the control electrodes of the power thyristors 19, 20 receive trigger pulses, the duration of which is constant throughout the entire range of resistance of the resistor 2.
