摘要

FIELD: pulse electronics.;SUBSTANCE: invention relates to pulsed electronics and can be used in electronic systems of automatic control, in robotics and telecommunication systems. For this purpose, proposed is time-pulse UIC voltage with pulse-width modulation function, consisting of four operational amplifiers, on which integrator is realized, a regenerative comparator and two voltage repeaters, a four-channel analogue switch and three inputs, is required to connect two input voltages and select a conversion function. If an electroconductive bridge is not connected to the third input, the converter performs conversion of the quotient of dividing the two input voltages into the frequency of the output pulses and in the time interval, if the terminals of the third input are short-circuited by a jumper, the signal terminal of the first input is connected through a resistor to the inverting input of the operational amplifier of the integrator and a pulse-width modulation function will be performed.;EFFECT: technical result is significant expansion of functional capabilities of universal integrating converter (UIC) due to fact that declared universal integrating converter with PWM function (UIC-PWM) can perform all three types of major conversion functions in electronics: conversion of input voltage to frequency of output rectangular pulses, in time interval, into pulse repetition pulses and all these types of conversion with simultaneous performance of arithmetic division operation, without changing the UIC-PWM electrical circuit and without using stable current sources and / or a stable reference voltage source.;1 cl, 4 dwg
