Abstract

Układ zasilający, zwłaszcza w licznikach energii elektrycznej, zawierający transformator sieciowy, prostownik i kondensator filtrujący, charakteryzuje sią tym, że początek lub koniec uzwojenia pierwotnego (p) transformatora (TR) połączony jest z anodą diody prostowniczej (D2), katodą diody prostowniczej (D3), pierwszym zaciskiem diody zabezpieczającej (D1) oraz pierwszym zaciskiem rezystora (R1). Drugi zacisk rezystora (R1) połączony jest z bazą tranzystora (Q1). Katoda diody prostowniczej (D2) połączona jest z wyjściem dodatnim (+) prostownika (BR) i katodą diody prostowniczej (D4), zaś anoda diody prostowniczej (D3) połączona jest z emiterem tranzystora (Q1) oraz zaciskiem ujemnym kondensatora (C1). Anoda diody prostowniczej (D4) połączona jest z dodatnim zaciskiem kondensatora (C1) oraz z katodą diody prostowniczej (D5). Drugi zacisk diody zabezpieczającej (D1), kolektor tranzystora (Q1) i anoda diody prostowniczej (D5) są połączone z masą. W odmianie wynalazku zamiast transformatora sieciowego i prostownika układ zasilający zawiera dwójnik szeregowy, który może stanowić dowolne połączenie rezystorów i/lub kondensatorów i/lub cewek indukcyjnych.The power supply system, especially in electricity meters, containing a network transformer, rectifier and filtering capacitor, is characterized by the fact that the beginning or end of the primary winding (p) of the transformer (TR) is connected to the rectifier diode anode (D2), the rectifier cathode (D3) ), the first terminal of the protection diode (D1) and the first terminal of the resistor (R1). The second terminal of the resistor (R1) is connected to the transistor base (Q1). The rectifier diode (D2) is connected to the positive output (+) of the rectifier (BR) and the rectifier diode (D4), while the rectifier diode (D3) is connected to the emitter of the transistor (Q1) and the negative terminal of the capacitor (C1). The rectifier diode anode (D4) is connected to the positive capacitor terminal (C1) and the rectifier diode cathode (D5). The second protective diode terminal (D1), transistor collector (Q1) and rectifier diode anode (D5) are connected to ground. In a variant of the invention, instead of the mains transformer and rectifier, the power supply system includes a serial binary that can be any combination of resistors and / or capacitors and / or inductors.
