The invention relates to a pulse technique and can be used in devices for generating modulating pulses for high-frequency oscillators, in particular

for M-type microwave oscillators, which are prone to breakdown (sparking) under certain conditions.

When a control pulse arrives from the output of the generator 8 control pulses through the separation capacitor 7 into the grid of the modulator lamp 6, the latter is switched on and the energy storage device 3 is discharged to the load 5 (microwave generator), the voltage pulse on which is blocked

The aim of the invention is to raise diode 16. Bypassing the controller.

efficiency and simplified generator design.

The drawing shows a diagram of the generator.

The generator contains a source of 1 liter, between the potential and common bus of which are connected in series the charging resistor 2, drive 3 knowledge, charge diode 4 and load 5, shunted by charge diode 4, switching element is connected between the input of the energy carrier 3 and the common bus 6 on a modulator lamp, the control input of which is connected via a coupling capacitor 7 to the output of the generator 8 control pulses and, via a series-connected coupling resistor 9 and the main bias source 10, to general tire Between the output of the control pulse generator 8 and the total length, a switch 11 is connected, the control input of which through a resistor 12 is connected to a common bus, and through series-connected capacitor 13, the limiting resistor 14 is connected to an additional bias source 15. To the common point of connection of the capacitor 13 and the limiting resistor 14 is connected the cathode of the diode 16, the anode of which is connected to the load 5.

The generator works as follows.

the pulse on the grid of the modulator lamp 6 by the bias source 10 is prevented by a limiting resistor 9 with a resistance of significant magnitude

1G Upon termination of the control pulse on the grid of the modulator lamp 6, the latter is locked and breaks the circuit of the flow of current pulses from the energy storage device 3 into the load

20 KU 5. V. For further operation of the generator, the indicated processes are repeated.

If in the process of applying the impulse to the load 5, its arcing (breakdown) occurs, then the voltage across it is sharply

2 falls, the diode 16 is unlocked, and the capacitor 13 is discharged to the control electrode of the switch 11 along the circuit: the sparking load 5 is the diode 16. As a result, the switch 11 is turned on and shunts

30 is the output of the control pulse generator 8, due to which the modular lamp 6 is locked and disconnects the load 5 from the energy storage 3. Voltage additional source 15 bias

35 in this case is allocated at resistor 14.

Subsequently, the voltage on the generator 13 is restored, the key 1 is locked and the generator is prepared

40 to further work.

f

In the event that the magnitude of the voltage of the main bias source 10 is sufficient to unlock the diode 16 V

In the pause between the control pulse 45, the moment of arcing of the load 5, then from the power source 1 through the charging resistor 2 and the charging diode 4, the power storage device 3 charges. The modulator lamp 6 is locked by the voltage of the main source 1 O at this time. the bias applied through the separation resistor 9 to its control grid. The capacitor 13 through the resistor 12 and the limiting resistor 14 is charged to the auxiliary voltage source 15 bias. The key 11 is locked and the capacitor 7 is charged until the voltage of the main source 10 is shifted.

As an additional bias source 15, the primary bias source 10 can be used. The resistor 14 in this case must be connected to the potential output of the main bias source 10.
