FIELD: secondary power supplies. SUBSTANCE: system has three-phase transformer and three- phase diode rectifier; first like-polarity leads of rectifier diodes are connected to respective phase leads of transformer secondary winding and their second like-polarity leads are interconnected; novelty is that introduced in addition are one more diode and long line whose first wire leads are connected to second like-polarity leads of rectifier diodes and to one of phase leads of transformer secondary winding, respectively, while second wire leads of long line are used as load-connection leads with additional diode inserted between them so that second like-polarity leads of rectifier are connected to long-line wire lead to which like-polarity lead of additional diode is connected. EFFECT: improved design. 3 dwg
