The invention relates to a pulse technique and can be used in automatic control and regulation systems, as well as in various fields of experimental physics.

The purpose of the invention is to reduce power consumption and increase reliability of operation by eliminating current surge at the pulse front.

The drawing is an electrical block diagram of the device.

The current pulse shaper contains a current generator 1, a power source 2, the first 3 and second 4 keys whose inputs are interconnected, and the output of the first one is connected through the load 5 to a common bus of the power supply 2, controlling 6 and clock 7 input buses. The first input of the programmable timer 8 is connected to the control bus 6, and the second - to the clock ohm 7, the first output is connected to the first input of the BANNER element 9, and the second output to the second input of the BELT element 9 and the control input of the first key 3, controlling the input of the second key 4 is connected to the input of the BANCH element 9, and the output through the resistor 10 is connected to the common bus of the power source 2 and the output of the current generator 1, whose input is connected to the positive bus of the power source 2, the negative bus of which is connected to the input of the first key 3 .

The shaper works as follows.

If at the outputs of the programmable timer 8 the mode from busbars 6 and 7 is set, when there are no control signals, the potentials at the control inputs of the first 3 and second 4 keys are close to zero, then both keys 3 and 4 are closed and, therefore, the current through the resistor 10 and load 5 does not leak.

The formation of a current pulse in the load circuit 5 is carried out in two stages. On the first timer, the control signal forms a logical 1 on the first (non-inverting) input of element 9 BAN, on the second (inverting) input — a logical O., On input

Element 9 BANGE appears at the logical level 1, unlocking the second switch 4, while in the circuit - positive supply source 2 bus, current generator 1, resistor 10, second switch 4, negative power supply 2 bus - current begins to flow.

After a certain period of time equal to the time of the end of transients in this circuit, timer 8 generates a control signal at its second output, while the second key 4 through the BAN 9 element closes and the first key 3 opens simultaneously and the Current from the resistor 10 key 4 switches in the key chain 3 and load.

As a timer, you can use the BIS КР 580 ВИ53 timer, the first and the second outputs of which are connected via inverters.
