SU123768A1 - Method for controlling key triode of one-pass shift register on magnetic cores and device for performing method - Google Patents

Description

A method is proposed for controlling the key triode in the discharge circuit of the capacitors of the one-pass shift register, made of ferrites with a rectangular hysteresser loop.

In the well-known method of controlling the KTK.Chev Trio pod.pedpii in the absence of clocks .1Co15 and is in the open state due to the power of its base by a constant switching from the source of mis1. The triode is energized by a blocking voltage pulse. Thus, the key triode consumes energy both between clock pulses and at the time of the clock pulses. In the first case, the energy is consumed from the DC source to keep the triode in an open state, and in the second case the energy from the clock source pulses is consumed to transfer the node from an open state to a closed and kept triode in a closed time. action clock pulse.

In the proposed procedure, the key triode, both at the time of the clock pulse and in the absence of the latter, is in the closed state and opens with a special current pulse fed to the base of the key triode at the end of the clock pulse in nm, for the time required for rewriting. 5O) from the storage capacitor to the next torus.

To control by this method, it is proposed to use the reverse pulse arising in the transformer windings;) and blocking the generator or pulse amplifiers, which, for the purpose of overvoltage on the triode collector, o6bi4iio is damped by a diode.

The drawing shows a diagram of an apparatus for carrying out a method for controlling a key triode without expenditure of useful energy, i.e., controlling a reverse, previously unused pulse / blocking.
