Quasi-resonant voltage transducer

The invention relates to the electrical engineering and is meant for creation of powerful, adjustable resonance voltage transducers of different application with a wide turn-down of load resistance and voltage.The quasi-resonant voltage transducer comprises a controlled driving generator (4), one output of which is connected to the input of converter module (1), made in the form of a current source with limited maximum value of the output voltage and with the nominal value of resistance R1 of its load, the outputs of which are connected to a load (3) with the nominal RNOM and maximum RMAX resistance values. The traducer comprises additionally the second converter module (2), the input of which is connected to the second output of the controlled driving generator (4) and connected parallel to the first one, identical with it, with the same maximum value of the output voltage and optimum resistance R2 value of its load, which is chosenequal to the maximum RMAX value of load (3), and the nominal RNOM resistance value of load (3) is chosen equal to the R1 and R2 value connected in parallel. The transducer also comprises a control unit (5), including a reference voltage source (6), the output of which is connected to one of the inputs of an error amplifier (7), the second input of which is connected to the load (3), and its output is connected to the control input of the driving generator (4) and by means of polarity choice diodes (8, 9) is connected to the inputs of a reversible counter (10), the outputs of which are connected to the inputs of a decoder (11), the outputs of which are connected to the inputs of the converter modules (1, 2). Invenţia se referă la electrotehnică şi este destinată pentru realizarea convertizoarelor de tensiune de mare capacitate cu cvasirezonanţă , reglabil, cu aplicare diversă, cu un diapazon larg de reglare a rezistenţei sarcinii şi a tensiunii.Convertizorul de tensiune cu cvasirezonanţă conţine un generator de comandă dirijat (4), o ieşire a căruia este conectată la intrarea unui modul de convertizare (1), executat în forma unei surse de curent cu valoarea tensiunii de ieşire maximă limitată şi cu valoarea optimă a rezistenţei R1 sarcinii sale, ieşirile căruia sunt conectate la o sarcină (3) cu valoarearezistenţei nominală RNOMşi maximă RMAX .Convertizorul conţinesuplimentarun al doilea modul de convertizare (2), intrarea căruia este conectată la a doua ieşire a generatorului de comandă dirijat (4) şi conectat paralel primului,
