FIELD: electrical engineering; dc power supply for electrical metal-working installations. SUBSTANCE: power supply has diode groups of three- phase bridge rectifiers connected in series and in parallel by means of controllable diodes whose anodes are connected to ac leads of one bridge set and cathodes, to like-phase leads of other rectifier set. Connected to opposite secondary-winding leads of respective transformer phases are ac leads of sets being connected. Number of bridge sets being connected is unlimited. EFFECT: simplified design, enhanced reliability, enlarged capability of matching power supply and load parameters. 7 cl, 8 dwg
