Abstract
Inventia face parte din domeniul autotronicii si se refera la un regulator de tensiune electronic utilizat pentru comanda curentului de excitatii a unui alternator în scopul mentinerii constante a tensiunii de încarcare a bateriei de acumulatori. Regulatorul de tensiune electronic este constituit dintr-un circuit integrat stabilizator de tensiune (A) de tipul uA723 alimentat la tensiunea bateriei si avînd anodul diodei dintr-o retea rezistiva de fixare a tensiunii alcatuita din divizorul potentiometric conectat la tensiunea bateriei avînd mijlocul rezistentei semireglabile conectat la intrarea inversoare a comparatorului intern al circuitului integrat format din rezistentele si tranzistorii dintr-o retea de reactie alcatuita din condensatorul de reactie nativa de la iesirea la intrarea inversoare a comparatorului intern si din reteaua de reactie pozitiva de la iesirea regulatorului la intrarea neinversoare dintr-un etaj de protectie la supracurent compus dintr-un din tranzistorul a carui jonctiune baza-emitator este polarizata de rezistenta înseriata cu colectorul tranzistorului dintr-un element de protectie la impulsuri negative de tensiune ce apar la întreruperea curentului de excitatie al alternatorului constituit din dioda si dintr-un element de protectie la impulsurile parazite ale tensiunii bateriei format din condensatorul de cuplare. Regulatorul de tensiune electronic poate echipa autovehiculele la care încarcarea bateriei se realizeaza cu un alternator, atît ca element distinct cît si ca element încorporat alternatorului.The invention is part of the automotive field and relates to an electronic voltage regulator used to control the excitation current of an alternator in order to maintain the battery charge voltage constantly. The electronic voltage regulator consists of an integrated voltage-stabilizing circuit (A) of the type uA723 fed to the battery voltage and having the diode anode in a resistive voltage clamping network consisting of a potentiometrically divisible battery voltage connected to the connected semipermeable resistor means at the inverse input of the internal comparator of the integrated circuit consisting of resistors and transistors from a reaction network made up of the native reaction capacitor at the output to the inverter input of the internal comparator and the positive feedback network from the controller output to the non- a overcurrent protection stage composed of one of the transistor whose base-emitter junction is polarized by the transistor collector resistance of a protective element to negative voltage pulses occurring at the interruption of the excitation current of the alternator constituted by d iodine and a protective element to the parasitic pulses of the battery voltage formed by the coupling capacitor. The electronic voltage regulator can equip cars where the battery is charged with an alternator, both as a distinctive element and as an element incorporated in the alternator.
