Abstract
Inventia se refera la un convertor curent alternativ / curent continuu de precizie destinat conversiei tensiunii alternative într-o tensiune continua în vederea masurarii, utilizat în voltmetre de precizie. Redresarea tensiunii alternative este realizata cu ajutorul unui comutator electronic (comandat de un etaj de sesizare a polaritatii tensiunii) care transmite tensiunea de intrare numai pentru una din polaritasile acesteia, realizându-se o redresare monoalternanta, dupa care urmeaza o filtrare a tensiunii obtinute. Convertorul poate fi utilizat în voltmetrele electronice de precizie destinate masurarii tensiunilor alternative.The invention relates to an AC / DC precision converter for converting alternating voltage into a continuous voltage for measurement, used in precision voltmeters. Alternative voltage rectification is achieved by means of an electronic switch (commanded by a voltage polarity reference stage) which transmits the input voltage only to one of its polarities, achieving a mono-alternating rectifier, followed by a voltage filtering. The converter can be used in precision electronic voltmeters designed to measure alternate voltages.
