Sparking pulse formers are known, containing a relay switch, the winding of which is connected to the negative pole of the power supply through one end of the power supply through time, and the power supply to the positive pole of the power supply and to the disconnecting contacts of the same switch to negative pole of the state food authority JV.

A disadvantage of the known cpopN-HpoBail is that the closed loop closure state switches the switch. It must be at least 1 time before the co-capacitor is loaded until the voltage J is sufficient for the relay to operate. Otherwise, a malfunction of the driver will occur, since pos.

The drawing shows a circuit diagram of a paired pulse former.

The paired pulse shaper includes a switch 1, the switching contact 2 of which is connected to the first terminal of the winding 3 of a polarized relay, another terminal of the winding 3 of which is connected via a electrolytic capacitor 4 to a negative power supply 5, and also a transistor 6 n, the collector of which is connected to the positive bus of the source 5 pita} sh, and the emitter through the disconnecting contact 7 of the switch 1 to the first terminal of the winding 3 of the polarized relay connected to the anode of the third diode 8, whose cathode connected to the base of transistor 6 and to the first output of an additional closing contact 9 of a polarized relay, the base of transistor 6 being connected through the input resistor 10 to the positive power supply 5, and the other output of the closing contact 9 of the polarized relay is connected to the negative power supply 5 bus , and through the switch; k; crccc contact 11 of the switch 1 to the first terminal of the winding - 3 polarized relays. The outputs form a sla-kat make contacts 12 and 13 of the polarized relay. Adjusting the duration of the output pulses is corrected, consisting of the first and second diodes 14 and 15, and the variables of the first 16 and second 17 resistors.

Shaper paired pulse works as follows.

In the initial state, the opening contact 7 of the switch 1 is closed, the contacts 9 are open; 12, and 13 of the polarized relay, the electrolytic capacitor A is charged before the voltage of the power source 5 due to the opening at the moment the power of the transistor 6 is turned on, the winding 3 of the polarized relay is de-energized. When the closing contact 1 i of the switch 1 is closed, the discharge current of the electrolytic capacitor 4 begins to flow through the winding 3 of the polarized relay. The polarized relay operates and its closing contacts 9 and 12 close. This state of the circuit corresponds to the formation

first pulse in a series of two pulses. A series-connected diode 8 and a closed closing contact 9 of a polarized relay shunt close the closing contact 1 1 of the switch 1. When the closing contact 11 of the switch 1 is opened before the discharge of the electrolytic capacitor 4 ends,

the discharge of the electrolytic capacitor 4 continues through the winding 3 of the polarized relay due to the closed state of its closing contact 9. At the same time, until the end of the discharge of the electrolytic capacitor 4, the transnotor 6 is locked due to the closed state of the closing contact 9 of the polarized relay and the presence of a charged electrolytic capacitor 4 in the emitter circuit. At the end and discharge of the electrolytic capacitor 4 about 5ka 3 of the polarized relay, the power contacts are closed and its closing contacts 9 and 12 open. In this case, the transistor b opens due to the flow of a portion of the charge current of the electrolytic capacitor 4 through the er-pter junction of transistor 6 and

resistor 10, due to the opening

charge electrolytic capacitor 4, which is triggered by a polarized relay. At the same time, its IS-3 contact closes.

which corresponds to the formation of a second impulse in a series of two pulses. Upon completion of the charging process of the electrolytic capacitor 4, the winding 3 of the polarized relay is de-energized and its contact 13 is opened. The electrolytic capacitor 4 remains in the charged state until the beginning of the next operating cycle. If the charge of the electrolytic capacitor 4 decreases for any reason, it is recharged along the circuit: the positive pole of the source 5 of the power j the transistor 6j of the closed break contact 7 of the switch 1,

winding 3 of a polarized relay, positive plate of electrolytic capacitor 4, negative cover of electrolytic capacitor 45, negative pole of power supply 5. Since when charging an electrolytic capacitor 4, the charge current is insignificant and does not reach values sufficient for
