<p>The invention relates to a transformerless supply circuit, especially for rail vehicles. According to the invention, a plurality of line-side converters (1, 2, 3) is arranged which each have a line-side four-quadrant controller (11, 21, 31), an intermediate circuit condenser (12, 22, 32) connected in parallel thereto and a motor-side four-quadrant controller (13, 23, 33). Said line-side four-quadrant controllers (11, 21, 31) can be connected in series. The motor windings (16, 26, 36) of an alternate current generator are each connected directly to the output terminals (P1, P2) of a motor-side four-quadrant controller (13, 23, 33).</p> |
