транзисторе 2, на резисторе 12 и открытом тиристоре 3.transistor 2, the resistor 12 and open thyristor 3.
Падение напр жени на транзисторе 10 нарастает до тех пор, пока потенциал на базе транзистора Я который равен напр жению нагрузки , уменьшитс до величины, заданной опорным напр жением стабилитрона 8.The voltage drop across the transistor 10 increases as long as the potential at the base of the transistor I, which is equal to the load voltage, decreases to the value given by the reference voltage of the zener diode 8.
Если напр жение нагрузки меньше опорного , коллекторный ток транзистора 9 уменьшаетс , что ведет к увеличению базового тока транизстора 10 и уменьшению падени напр жени на этом транзисторе.If the load voltage is less than the reference voltage, the collector current of the transistor 9 decreases, which leads to an increase in the base current of the transistor 10 and a decrease in the voltage drop across this transistor.
Падение напр жени на транзисторе W уменьшаетс до тех нор, пока потенциал на базе транзистора 9 не вырастет до величины, заданной опорным напр жением стабилитрона 8.The voltage drop across the transistor W decreases until the potential at the base of transistor 9 increases to the value given by the reference voltage of the zener diode 8.
При подаче управл юпхего импульса на управл ющий вход тиристора 4 он н транзистор / открываютс , тиристор 3 и транзистор 2 закрываютс .When a control pulse is applied to the control input of the thyristor 4, it n transistor / opens, the thyristor 3 and transistor 2 close.
Положительный потенциал напр жени нагрузки подключаетс через днод 7 к базе транзистора 9. Дальнейша стабилизаци выходного напр жени не отличаетс от изложенной .The positive potential of the load voltage is connected through the bottom 7 to the base of the transistor 9. Further stabilization of the output voltage does not differ from that stated.
