COMBINED METHOD OF QUALITY INCREASE OF ELECTRIC POWER IN POWER SUPPLY SYSTEM FEEDING SERIES OF ALUMINIUM ELECTROLYZERS WITH CONTROLLED CURRENT Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: invention is intended to supply mighty D.C. services. It is aimed at quality increase of electric power in feeding system with simultaneous simplification of design of multiphase rectification circuits which include rectification units 13-15, converter transformers 7-12 and power transformers 4-6. These aims are achieved thanks to use of control parts of primary windings of converter transformers both for change (increase) of number of rectification phases and for control over load current in compliance with determined algorithm. EFFECT: increased quality of supplied electric power, simplification of design of rectification circuits. 2 cl, 1 dwg
