Description

Известны блокннг-генераторы с подачей запускающего импульса через каскад с катодным выходом, в которых, с целью их запуска дл  разрыва цепи поло сительной обратной св зи, используетс  отрицателькое напр жение, запирающее лампу блокинг-генератора по управл ющей сетке, когда цепь положительной обратной св зи рветс  либо запертым диодом, либо простым отключением одного из концов обмотки трансформатора. Недостатки подобных устройств заключаютс  в сложности схемы, требующей наличи  двух источников отрицательного смещени , и возможности возникновени  генерации в промежутках между . запускающими импульсами.Known block generators with a triggering pulse through a cathode output stage are known in which, in order to start them, to break a positive feedback circuit, a negative voltage is used that locks the blocking generator lamp over the control grid when the positive feedback circuit is Zv rvets or a locked diode, or simply disconnecting one of the ends of the transformer winding. The disadvantages of such devices are the complexity of the circuit, which requires the presence of two sources of negative bias, and the possibility of generation in the intervals between. triggering pulses.

В описываемом устройстве этк недостатки устранены тем, что обмотки трансформатора обратной св зи включены противофазно, а цепь положительной обратной св зи разомкнута.In the described device, these shortcomings are eliminated by the fact that the windings of the feedback transformer are turned on in antiphase and the positive feedback circuit is open.

Схема описываемого устройства приведена на чертеже. Обмотки трансфор.матора / обратной св зи включены так, что при отсутствии запускающего импульса цепь положительной обратной св зи разомкнута, приче.м положительна  обратна  св зь с анода на катод лампы генератора 2 компенсируетс  отрицательной обратной св зью, создаваемой посредством сопротивлени  R. Вследствие противофазного включени  обмоток трансформатора возникновение и усиление каких-либо колебаний в про.межугках между пусковыми импульсами исключаетс . При подаче запускающего импульса происходит коммутаци  обмоток . Образуетс  цепь положительной обратной св зи, вследствие чего создаютс  услови  дл  возникновени  блоккнг-процесса.The scheme of the described device shown in the drawing. The transformer / feedback windings are turned on so that in the absence of a triggering pulse, the positive feedback circuit is open, and the positive feedback from the anode to the cathode of the generator 2 lamp is compensated by the negative feedback created by resistance R. Due to antiphase switching on the transformer windings, the occurrence and amplification of any oscillations in the pro.mezhugki between the starting pulses is excluded. When a triggering pulse is applied, the windings are switched. A chain of positive feedback is formed, resulting in the creation of conditions for the occurrence of a block-process.
