<p>A circuit arrangement (1) for power distribution in a motor vehicle is described, which comprises a transformer (T1, T1a . . . T1n) having at least three transformer windings (W1, W1a . . . W1n, W2, W2a . . . W2n, W3, W3a . . . W3n). A first and second on-board supply inside the vehicle and a power supply which is outside the vehicle can be connected to the circuit arrangement (1), which supplies are coupled via the transformer windings (W1, W1a . . . W1n, W2, W2a . . . W2n, W3, W3a . . . W3n) and converters (UR1, UR2, UR2a . . . UR2n, UR3, UR3a . . . UR3n). The third converter (UR3, UR3a . . . UR3n) can be connected via a first change-over switch (US1, US1′) alternatively to the first on-board supply inside the vehicle or to the power supply outside the vehicle. A plurality of first converters (UR 1) and/or a plurality of second converters (UR2, UR2a . . . UR2n) and/or a plurality of third converters (UR3, UR3a . . . UR3n) each being connected to the transformer windings (W1, W1a . . . W1n, W2, W2a . . . W2n, W3, W3a . . . W3n) can be switched in series or in parallel are provided.</p> |
