STABILIZED KEY VOLTAGE CONVERTER Russian patent published in 2020 - IPC G05F1/565 

FIELD: conversion equipment.

SUBSTANCE: invention relates to conversion equipment, namely to secondary sources of power supply of functional equipment of telecommunication equipment and hydroacoustic equipment, including for power supply of remote consumers. Additionally, the device implements parametric stabilization of power supply voltage of remote consumer, connected to key voltage converter through cable connector with known through resistance due to corresponding shift of reference voltage by value, proportional load current and resistance of cable connector by using additional input of difference signal amplifier for connection of scalable voltage from additional output of feedback circuit by output current.

EFFECT: technical result is increased stability of secondary voltage and achievement of reliable operation at change of output current due to use of combined feedback (CF) by output voltage and output current, which provides increase in the CF depth in the rated operating mode and transition to the output current limitation in the overload mode by means of the current sensor, the current feedback circuit and the difference signal amplifier in the feedback circuit by the output voltage.
