Генератор работает следующим образом.The generator operates as follows.

При включении питания через резистор 2 начинает заряжаться конденсатор 1. Когда напряжение на конденсаторе 1 достигнет уровня срабатывания динистора 5, конденсатор 1 перезаряжается через обмотку 7, диод 6 и динистор 5. Последний выключается.When the power is turned on through the resistor 2, the capacitor 1 begins to charge. When the voltage on the capacitor 1 reaches the response level of the dinistor 5, the capacitor 1 is recharged through the winding 7, diode 6 and the dinistor 5. The latter is turned off.

При перезарядке конденсатора 1 его энергия передается конденсатору 11, от которого через резистор 12 заряжается конденсатор 13 малой емкости. Когда напряжение на конденсаWhen recharging the capacitor 1, its energy is transferred to the capacitor 11, from which a small capacitor 13 is charged through the resistor 12. When the voltage on the condensation

Затем заряд и разряд конденсатора 13 повторяются, пока напряжение на конденсаторе 11 не упадет ниже уровня срабатывания динистора' 5. Интервалы между импульса10 ми в пачке увеличиваются.1262698 * torus 13 will reach the response level of the dinistor 5, the capacitor 13 is discharged to the load 14 through the diode 15 and the dinistor 5, forming the first pulse from the packet. Then the charge and discharge of the capacitor 13 are repeated until the voltage across the capacitor 11 drops below the response level of the dynistor '5. The intervals between pulses 10 mi in the packet increase.
