Abstract

Inventia se refera la o metoda si un circuit de conversie curent-frecventa pentru o plaja larga de valori a curentului, utilizabile în industria electrotehnica. Metoda si circuitul de conversie curent-frecventa, conform inventiei, rezolva problema conversiei în frecventa a unui curent I indice x suprapus peste un curent de referinta I indice 0, într-o plaja larga a curentului I indice x, conversie ce se face în doua faze cu un numar minim de comutari a curentilor printr-un condensator, fara a schimba sensul de curgere a curentului I indice x prin condensator, în timp ce în cele doua faze curentul de eroare I indice e are sensuri diferite.
