1. A direct current converter circuit with transformer, rectifier and filter the in output circuit, characterised in that it consists of a reversely-conductive thyristor (TWP); the anode thereof is connected through a choke (L1) to the positive end of supply voltage and also to the serial two-terminal network which comprises the choke (L2) and a capacitor (C1); the other terminal thereof is connected to one terminal of capacitor (C2) and one terminal of capacitor (C3), the cathode of the said reversely-conductive thyristor (TWP) is connected with the other terminal of capacitor (C2) to the negative end of supply voltage and the primary winding terminal of the output circuit transformer, and the other terminal of capacitor (C3) is connected to the other terminal of the transformer (Tr) primary winding, while the reverse thyristor (TWP) gate-cathode terminals are connected to the output of the control generator (GS).<IMAGE>
