FIELD: conversion equipment.
SUBSTANCE: invention relates to conversion equipment, namely to secondary power sources with controlled output voltage for power-consuming equipment, including pulse modes of operation with capacitive energy storage. For this purpose, a control key voltage converter is proposed, comprising a phase-pulse converter connected by an input to a control bus, and direct and inverse outputs of master and slave channels to corresponding inputs of key power amplifier, power supply terminals of which are connected to power supply buses, and outputs through matching transformer with inputs of synchronous rectifier, as well as low-pass filter, which output is connected to output voltage bus and through voltage feedback circuit is connected to input of phase-pulse converter compensation, wherein it additionally includes current sensor, resolution circuit, relay element, current feedback circuit and capacitance accumulator.
EFFECT: high reliability of operation when expanding range of capabilities of using a controlled key voltage converter.
