Arrangement providing a 3-phase or 1-phase power stream It is described an arrangement (100, 300) for alternatively providing a 3-phase or a 1-phase power stream, comprising: a 3-phase power source (103, 303) having a first (105, 305), a second (107, 307) and a third (109, 309) power source output terminal; a switching section (111, 311) adapted to selectively provide from the three power source output terminals (105, 107, 109, 305, 307, 309) of the 3-phase power source: a 3-phase power stream at three arrangement output terminals (117, 119, 121, 317, 319, 321) or a 1-phase power stream at two arrangement output terminals (115, 123, 315, 323), different from the three arrangement output terminals (117, 119, 121, 317, 319, 321). |
