Description

one

The invention relates to the field of automation and computing.

Shift registers are known that contain a power source connected via a key controlled by a clock source with cells on thyristors connected by cathodes to the output winding of the transformer and a resistor, the transformer of each cell containing setting and clock windings that are connected in series with the corresponding windings of others the cells.

The proposed register differs from the known ones in that an additional winding is inserted in each transformer of the next cell, which is connected to the circuit of the control electrode of the previous cell thyristor counter-series with the output winding of the corresponding transformer.

This made it possible to increase the efficiency and reliability of the device.

The block diagram of the device shown in the drawing.

The device contains a power source 1 connected via a switch 2, controlled from a source of 3 clock pulses, with cells on thyristors 4, each of which is connected by cathodes to the output winding 5 of transformer 6 and resistor 7. Each transformer of the cell contains 5 and

clock 9 windings, which are connected in series with the corresponding windings of other cells, with additional winding 10 introduced into each transformer of the next cell, which is connected to the control electrode circuit of the previous cell of the previous cell with the output winding 5 of the corresponding transformer (5.

The device works as follows. Let the signal of the mounting winding 8 let the cores t in series of transformers 6 be transferred to a state defined by induction satanIN, with the exception of the first core, whose induction corresponds to the point -5s. Then, when the first clock pulse arrives from a 3 clock pulse source operating at a frequency / p / o (where m is the number of shift register cells), an output winding on the output winding 5 of transformer 6 appears, which enters the thyristor 4 through an additional winding 10 saturated transformer 6 and includes a thyristor

4, with the result that a signal appears on resistor 7, the shape of which depends on the selected switching system.

The signal of interference to the control transitions of other thyristors is not received, since it is compensated by the signal of interference that occurs

with the remagnetization of the transformer 6 in each subsequent cell of the shift register.

For example, when a clock pulse arrives at a winding 9 of a transformer 6, a pulse of interference occurs at the output winding 5 of the same transformer, which does not arrive at the control transition of the thyristor 4, as it is compensated by a similar pulse of interference that occurs at the additional winding 10 of the transformer the same clock pulse, since the additional winding 10 of the transformer and its output winding 5 are switched in opposite.

Similarly, taking into account the counter-sequential inclusion in the control circuits of the thyristors 4 windings of transformers 6 belonging to the two cells of the shift register, the interference in the base circuits of all thyristors is compensated.

When the thyristor 4 conducts a current, a constant signal arises at its base – cathode junction, the magnitude of which is equal to the voltage drop across the junction. Under the action of this signal, the current passes through the windings 10 and 5, the control transition of the thyristor 4 and the transformer

6, they re-magnetize from the state corresponding to the induction of "- | -Bs, to the state corresponding to the induction of" -Ss, as a result of which they are prepared for the remagnetization under the action of the next clock pulse. Further, the processes are repeated.
