Изобретение -относитс к радиотехнике, Mi , жет быть использовано в модул торах импульсных передающих устройств. Известны устройства, в которых используетс параллельный зар д накопительных конденсаторов через резисторы и последовательное их соединение с помощью ключей при разр де с цепью увеличени амплитуды формируемых импульсов 1 .The invention is related to radio engineering, Mi, is to be used in modulators of pulsed transmitting devices. Devices are known that utilize parallel charging of storage capacitors through resistors and sequentially connecting them with keys when discharging with an amplification circuit of the generated pulses 1.

Недостатком известных устройств вл ютс потери энергии на резисторах как при зар де накопительных конденсаторов, так и при их разр де за счет наличи тока источника питани через открытые разр дные ключи.A disadvantage of the known devices is the energy losses on the resistors both during the charging of the storage capacitors and during their discharge due to the presence of the current of the power source through the open bits of the switches.

Известен также генератор импульсов высокого напр жени , содержащий N каскадов, каждый из которых состоит из конденсатора, к верхней и нижней обкладке которого подключены соответственно первый и второй резисторы, цепь из ковденсатора и второго резистора защунтирована разр дным ключом, а второй резистор зашунтирован диодом в пр мом включении, вторые резисторы всех кас« кадов включены в последовательную цепь.Also known is a high voltage pulse generator containing N stages, each of which consists of a capacitor, the first and second resistors are connected to the upper and lower plates, respectively, the circuit from the capacitor and the second resistor is backed up with a dongle switch, and the second resistor is dioded by the diode When switched on, the second resistors of all cad cadas are connected in series.

первый вывод которой соединен с общей щиной , а второй - с нагрузкой 2.the first output of which is connected with the total thickness, and the second - with the load 2.

Недостатком известного устройства вл етс низкий КПД за счет потерь тока во врем формировани выходного импульса.A disadvantage of the known device is low efficiency due to current losses during the formation of the output pulse.

Целью изобретени вл етс повыщение КПД.The aim of the invention is to increase the efficiency.

Указанна цель достигаетс за счет того, что в генератор. импульсов высокого напр жеto ни , содержащий N каскадов, каждый из которых состоит из конденсатора, к верхней и нижней обкладке которого подключены соответственно первый и второй {Ьезисторы, цепь из конденсатора и второго резистора за15 шунтирована разр дным ключом, а второй резистор защунтирован диодом в пр мом включении, вторые резисторы всех каскадов включены в последовательную цепь, первый вывод которой соединен с общей шиной, а вто This goal is achieved due to the fact that the generator. high-voltage pulses, containing N stages, each of which consists of a capacitor, the first and second {bezistors, the circuit of the capacitor and the second resistor are connected to the upper and lower plates, and the second resistor is bypassed by the diode in the right switching on, the second resistors of all stages are connected to a series circuit, the first terminal of which is connected to the common bus, and

20 рой - с нагрузкой, в каждый каскад введен зар дный ключ, который соещшен последовательно с первым резистором, причем зар дные ключи всех каскадов включены последователь20 pounds - with a load, a charging switch is inserted into each cascade, which is connected in series with the first resistor, and the charging switches of all cascades are included in the sequence

Claims

Claim

The pulse generator operates as follows.

When the charging keys 2 are activated through the resistors 3 and diodes 7, the capacitors charge up to the voltage of the source 1. After that, the current through the charging keys stops and they close.

When the discharge keys 4 are activated, the discharge of the capacitors 5 begins through the switches 4 and the resistors 6. The voltages on the resistors 6 are applied in such a way that they close the diodes 7. Through the open switches 4, all the capacitors 5 are connected to each other and to the load 8 in series, i.e. through. load 8 is the discharge of series-connected capacitors 5.

With the simultaneous actuation and closing of all discharge keys 4, the pulse generator generates a rectangular high-voltage pulse with an amplitude equal to the sum of the voltages on the capacitors of all stages at the load, and when opened, 20
