Abstract

Convertorul curent-frecventa face parte din circuitele de masura si control ce realizeaza prelucrarea numerica a semnalelor analogice. Convertorul, conform inventiei, este alcatuit dintr-un amplificator electronic basculant, care are pe reactie o punte redresoare comandata de curentul de colector al tranzistorului unui optocuplor, având la intrare curentul de convertit, curent de colector ce impune valoarea marimii de reactie a amplificatorului, împreuna cu un condensator determinând bascularea marimii de iesire a amplificatorului, cu o frecventa proportionala cu valoarea curentului de convertit.The current-frequency converter is part of the measurement and control circuits that perform the numerical processing of analog signals. The converter according to the invention consists of an electronic dummy amplifier, which has a rectifier bridge controlled by the collector current of an optocoupler transistor, having the input current to be converted, a collector current that requires the amplifier's response magnitude, together with a capacitor causing the amplifier to output at a frequency proportional to the value of the converted current.
