Description

Отличие предлагаемого способа от известных состоит в том, что регулирование ширины импульсов осуществл етс  по значению ионного тока в сеточных цеп х.The difference of the proposed method from the known ones is that the adjustment of the pulse width is carried out according to the value of the ion current in the grid circuits.

Это обеспечивает ослабление распылени  сеток и повышает устойчивость работы преобразовател .This ensures that the spraying of the grids is weakened and increases the stability of the converter.

На чертеже изображена принципиальна  электрическа  схема, по сн юща  предлагаемый способ.The drawing shows a circuit diagram explaining the proposed method.

Генератор пр моугольных импульсов представл ет собой мультивибратор , собранный на лампах Л и Лз. Лампа Л работает в качестве усилител  мощности, а лампа Л служит дл  усилени  сигнала ощибки, по вл ющегос  при нарущении равенства между длительностью полуволны анодного тока и длительностью подачи положительного напр жени  на управл ющую сетку вентил . Дл  формировани  сигнала ощибки в генераторе используетс  изменение максимального значени  обратного тока, проход щего через сетку вентил , при смещении момента подхода анодного тока к нулю относительно момента подачи отрицательного напр жени  на управл ющую сетку вентил . При возникновении такого смещени  увеличиваетс  максимальное значение обратного тока, проход щего через сетку, а следовательно, и максимальное значение падени  напр жени  на сонротивлении в цепи катода лампы Лз.The square pulse generator is a multivibrator assembled on L and Lz lamps. Lamp L acts as a power amplifier, and lamp L serves to amplify a fault signal that occurs when the equality between the half-wave length of the anode current and the duration of the positive voltage applied to the control grid of the valve is violated. To generate an error signal in the generator, the change in the maximum value of the reverse current passing through the valve grid is used when the anode current approaches the zero current relative to the moment when the negative voltage is applied to the control grid of the valve. When such a displacement occurs, the maximum value of the reverse current passing through the grid increases, and consequently, the maximum value of the voltage drop across the resistance in the cathode circuit of the lamp Lz.

Генератор должен иметь такую посто нную времени цепи CiRi, чтобы за врем  паузы в импульсе падени  напр жени  на сопротивлении в цепи катода лампы Лз емкость Ci разр жалась незначительно. Тогда напр жение на емкости С, будет пропорционально максимальному значению обратного тока сетки вентил .The generator must have a time constant CiRi for such a time that during the pause in the impulse of the voltage drop across the resistance in the cathode circuit of the lamp Lz, the capacitance Ci is discharged slightly. Then the voltage across the capacitance C will be proportional to the maximum value of the return current of the valve grid.

При увеличении обратного тока сетки вентил  увеличитс  положительное падение напр жени  на емкости Ci, что приведет к увеличению анодного тока лампы Л, т. е. длительности импульсов, формируемых мультивибратором. При уменьщении длительности полуволны анодного тока максимальное значение обратного тока сетки вентил  будет уменьAs the return current of the grid increases, the valve will increase the positive voltage drop on the capacitance Ci, which will lead to an increase in the anode current of the lamp L, i.e., the duration of the pulses generated by the multivibrator. When reducing the duration of the half-wave of the anode current, the maximum value of the reverse current of the grid of the valve will decrease
