Description

Systems with the use of magnetic cores with rectangular, loop, and hysteresis are widely used in radio engineering, automation, and computer technology. Of great interest for various fields of technology are closed ring registers.

Ferrite-diode and ferrite-triode ring registers are known. In ferrite-diode ring registers, clock pulses are used, whose parameters (amplitude, duration, slope of the pediment, etc.) have certain requirements. In addition, the source of clock pulses must have considerable power. In ferrite-triode ring registers, clock pulses may also have small energy sufficient to cause a regenerative process. However, their disadvantage is a large number of semiconductor triodes.

To obtain the ability to operate from a single-cycle trigger circuit and increase efficiency and reduce the number of triodes in the proposed two-stroke ferrite-triode ring register, each write-off branch of the path forms in conjunction with the semiconductor triode blocking oscillator. The circuit input is connected to the bases and both triodes.

The drawing shows a schematic diagram of the device.

The circuit is a push-pull ring register with a diode in a two-port communication. Register cores are divided into two groups: № 1, № 3 and № 2, № 4. The set of cores of each group, together with the triode belonging to this group, forms the scheme of the waiting blocking generator. The windings We of the collector circuit of the triode and the windings of the Woe base circuit are connected in series in each group of cores. The windings of the base circuit of the triode provide the positive feedback necessary for the development of the blocking sequence No. 151891-2. The bases of both triodes are connected to the input of the circuit. The standby mode of the blocking generators is carried out using a voltage divider formed by capacitor C, diode D and Resistance R.

Consider the principle of the proposed register.

Let “1 be recorded on core number 1. On all other cores,“ O. Clock pulses arrive simultaneously to the bases of the triodes of both blocking generators. The incoming pulse will trigger the blocking generator of the group in which one of the cores contains “1.

In the blocking process, the state "1" from this core is written off. The voltage pulse that occurred on the winding enters the RHI load. The voltage pulse arising on the winding reverses the next core N ° 2 from the state "O to state" 1. When the next clock pulse arrives, a second blocking generator is prepared for operation. The process is repeated. When remagnetizing the core No. 2 from the state "1 to the state" O on the WH winding, a voltage pulse of such polarity arises that it is possible to magnetize the core No. 1 from the state "O to the state" 1. This is prevented by the diode Dj standing in the quadrupole connection between the core No. 1 and No. 2. Diode D is closed if the voltage across the winding is less than b. The resistance Rn is limited by the current in the magnetic reversal circuit.

For the operation of the known two-stroke ring registers, it is necessary to alternately feed the writing-off pulses into each of the two groups of cores, for which they use a generator that generates pulses that are shifted in time in two channels.

In the proposed scheme, the order of distribution of the pulses, which write off 1 is necessary, is automatically carried out by groups of servers.
