Abstract

Inventia se refera la un dispozitiv pentru reglarea turatiei motoarelor asincrone trifazate compus dintr-un redresor, un chopper si un invertor astfel alimentat încît raportul tensiune-frecventa sa fie prestabilit. pentru reglarea tensiunii se prevede un transformator functional, asigurîndu-se o caracteristica optima a tensiunii functie de frecventa, iar pentru protectia la curent a chopperului care realizeaza blocarea chopperului asincron cu frecventa de choppere si un circuit de protectie la curent a invertorului.
