Description

A set of logical devices is known, based on the principle of the action of a half-wave, high-speed magnetic amplifier and consisting of elements that perform the functions of AND and OR and HF.T.

From these elements, supplemented by "memory and" time delay, circuits are synthesized on magnetic logic devices.

Along with three exponential elementary functions, among the main functions of the algebra of logic is the "equivalence: equivalence).

Also known is a magnetic logic device on a core with a rectangular hysteresis loop having a working winding, in series with which a diode, a resistance and a source of alternating voltage, and two control windings are included.

The proposed device is characterized in that the "plus and the source of the reference voltage are connected to the beginning and the end of the control windings, one of which is connected through a resistance and two parallel-connected branches containing a diode and resistance, connected to the" minus of the voltage source to which and the second winding through the diode and resistance, which serves to connect both inputs of the device using a separation diode-i circuit.

This allows equipment to be reduced and the performance to be increased when the "equivalence" operation is performed.

FIG. 1 shows the scheme of the proposed device, the table corresponding to the logical function “equivalence and its relativistic co-tact model; in fig. 2 - the relay-contact model of the device is represented by the wiring diagram of two relays, each having one normally open and one normally closed contact. Here a and b are input parameters of the relay.

The device is made on a toroidal core of a material with a rectangular hysteresis loop and has three windings: two sets No. 149259-- 2 equal to Wa and Xb - and working Wp, and the winding Wa by parameters is equal to the winding Wi Polarity of working U and reference U for example Chepea Pas FIGS. 1 is not circled for the control half period, and circled for the working half (working half period: half period in which BP the rectifier of the working circuit conducts, and the control one when the rectifier B does not hold. The same applies to polarity signals a and 6 controllers.

R1z due to the different polarity of the control windings Wa and W / in the control half-period of the mode with sigpals and 6 0 demagnetized core is impossible if the demagnetizing and magnetizing circuit resistances are equal or different by such a value that the condition is met (ia-gb } / s, where 4, and / - are the instantaneous values of the currents in the windings W and W in the control half-period; / ,. is the conditional coercive current.

In this case, the currents in the control windings are limited only by the active resistances of the circuits, which is a condition for determining the resistance values Ra, Kb, Co and R so that the currents in the windings Wa and Wh do not exceed the allowable values for this section of the winding wire.

In the working half-period there will be a half-way, and therefore, with and b 0 we get (1).

If a 1 and, then in the control half-period the signal a creates voltage on the resistances Ko and KaE If Up, a Uftg U, then with the values indicated in FIG. 1 field degaussing along the branch S; -K „of the winding circuit W is impossible, as well as magnetization along the winding W is impossible. At the same time, the B2-Ri branch of the demagnetizing circuit is unlocked, as a signal, therefore the core will be demagnetized from plus fa to minus “. (f, is the saturation flow of an ideal rectangular hysteresis loop. The demagnetization process of the core will cause the appearance of emf transformations in the windings W ,, and W. In the winding circuit, the emf of the transformation is added to the reference voltage. Therefore, in order to block the winding circuit, a condition is required in which and „2U.

Since in the control half-period the core is demagnetized from plus f. 0, we get f / 0 ().

The operation of the device in) is not fundamentally and fundamentally different from the mode and, if (, therefore with and b we get ().

The current passing through the valves B, B, B and B should not exceed the permissible, which is the second condition for determining the magnitude of the resistances, K and K, In the control half period of the mode and 6 1 the demagnetization, the magnetization of the core, therefore at the end the controlling half-period, the magnetic state of the core will be the same as at the end of the working half-period, i.e., plus F1. Consequently, for and we obtain b {a - b).

In the device circuit included load.
