The arrangements (A, B) have three-phase alternating current transformers with three secondary-side coils (L21, L22, L23) arranged on sidepieces of transformer cores. Three single-phase alternating current transformers have a secondary-side coil arranged on the sidepieces of transformer cores. A rectifier has current converter valves (D1, D2, D3) connected with the secondary-side coils to the rectifier. Power controllers e.g. thyristors, change a transmission ratio of the three-phase alternating current transformer or transmission ratios of the single-phase transformers. An independent claim is also included for an arrangement comprising power supply arrangements. |
