Abstract
Изобретение относитс к преобразовательной технике. Цель изобретени - расширение диапазона регулировани и области применени . В конце каждого полупериода питающего напр жени с помощью узла 9 обнулени конденсатора 10 врем задающей RC-цепочки производитс полный разр д конденсатора 10. Благодар этому во всем диапазоне регулировани фазовый угол включени силового тиристора 2 пропорционален величине напр жени задани . Дополнительный выпр митель 3 разграничивает цепи схемы 6 управлени силоаым тиристором и цепь нагрузки. 3 ил.The invention relates to a converter technique. The purpose of the invention is to expand the range of control and scope. At the end of each half-cycle of the supply voltage, using the capacitor-zeroing unit 9, the time of the driving RC-chain is fully discharged to the capacitor 10. Due to this, the entire turn-on angle of the power thyristor 2 is proportional to the setpoint voltage. An additional rectifier 3 distinguishes between the circuits of the power thyristor control circuit 6 and the load circuit. 3 il.
