Description
Повторители на тиристорах известны.Repeaters on thyristors are known.
Предложенный повторитель отличаетс тем, что катод первого и управл ющий электрод второго тиристоров соединены с помощью двух сопротивлений и стабилитрона.The proposed repeater is characterized in that the cathode of the first and the control electrode of the second thyristor are connected by means of two resistances and a zener diode.
Это позвол ет усилить отрицательные импульсы без изменени их длительности.This allows the negative pulses to be amplified without changing their duration.
Принципиальна схема устройства представлена на чертеже.A schematic diagram of the device is shown in the drawing.
Она содержит два тиристора 1 и 2, стабилитрон 3, конденсатор 4 и диод 5.It contains two thyristors 1 and 2, a zener diode 3, a capacitor 4 and a diode 5.
При включении напр жени питани напр жение в точке 6 поднимаетс выше напр жени пробо стабилитрона 3 и напр жени катод- управл ющий электрод тиристора 2.When the supply voltage is switched on, the voltage at point 6 rises above the voltage of the breakdown of Zener diode 3 and the voltage of the cathode control electrode of the thyristor 2.
При этом тиристор 2 включаетс . Ток управл ющего электрода тиристора 2 течет лищь до момента включени последнего. После включени потенциал анода тиристора падает почти до нул , и этот ток прекращаетс . Тиристор 1 выключен до прихода в точку 7 отрицательного сигнала. При этом тиристор /In this case, the thyristor 2 is turned on. The current of the control electrode of the thyristor 2 flows only until the latter is turned on. After switching on, the potential of the thyristor anode drops almost to zero, and this current stops. Thyristor 1 is turned off before the negative signal arrives at point 7. In this case, the thyristor /
включитс , конденсатор 4 своим разр дным током выключит тиристор 2. Потенциал точки 6 при этом снижаетс настолько, что стабилитрон 3 включитьс не может и, следовательно , тиристор 2 также не включаетс .on, the capacitor 4 with its discharge current turns off the thyristor 2. The potential of point 6 at the same time decreases so much that the zener diode 3 cannot turn on and, therefore, the thyristor 2 also does not turn on.
При исчезновении входного сигнала потенциал- точки 6 вновь поднимаетс , тиристор 2 включаетс , а тиристор / выключаетс . Таким образом, схема приходит в исходное состо ние , а на аноде тиристора / формируетс мощный отрицательный импульс, по длительности равный входному сигналу.With the disappearance of the input signal, the potential-point 6 is raised again, the thyristor 2 is turned on and the thyristor is turned off. Thus, the circuit returns to its original state, and a powerful negative pulse is formed at the anode of the thyristor /, equal in duration to the input signal.
Предмет изобретени Subject invention
Повторитель на тиристорах, выполненный на основе параллельного двухтиристорного инвертора, отличающийс тем, что, с целью усиле1п-1Я отрицательных импульсов без изменени их длительности, он содержит стабилитрон , анод которого соединен с управл ющим электродом одного тиристора, а катод через сопротивление - с входом устройства.A repeater on thyristors made on the basis of a parallel two-thyristor inverter, characterized in that, in order to amplify negative impulses without changing their duration, it contains a zener diode, the anode of which is connected to the control electrode of one thyristor, and the cathode through the resistance to the device input .
