CONTROL CIRCUIT Russian patent published in 2012 - IPC H03K19/00 

FIELD: radio engineering.

SUBSTANCE: control circuit for comparing two signal sequences and generating a dynamic signal upon equivalence of these sequences, having two signal amplifiers connected to a diode bridge, first and second optronic drivers connected in series to an output stage, having a pulse transformer with two output coils, one with a forward line for generating the control frequency and the other with reverse line for generating supply voltage for the first optronic driver. The circuit also has a buffer stage which generates a short voltage pulse for starting up the circuit and allowing passage of clock frequency to the second optronic driver for controlling the output stage. Two signal amplifiers transmit antiphase dynamic signals to the diode bridge, at the output of which supply voltage is generated for the second optronic driver and the output stage.

EFFECT: high reliability and simplification of the device due to exclusion of additional power supplies and powering the circuit with two antiphase signals only.
