  • the present invention relates to a transformer solution
  • transformer-connected feeder circuits for rail vehicles, in which the energy from the contact wire is withdrawn in a single phase at 15 kV, 16 2/3 Hz or 25 kV, 50 Hz and fed to the main transformer via the path current collector and main switch.
  • the main transformer has four largely decoupled traction windings on the low voltage side.
  • the adjoining four-quadrant actuators as network actuators ensure that almost exclusively active power can be drawn from the network and electrical braking energy can also be fed back into the network as pure active power. Capacitors ensure sufficient smoothing of the DC link voltage.
  • a problem here is that in addition to weight and volume restrictions, there are high transformer costs and that the transformer also requires a large cooling system with heat exchangers for ambient air.
  • a transformerless feed circuit was developed, as described for example in EP 0 670 236 AI.
  • This feed-in circuit has a plurality of four-quadrant actuators electrically connected in series on the input side, each of which is followed by an intermediate circuit capacitor bank on the output side.
  • Each DC link capacitor battery supplies an inverter, which is connected on the output side to a primary winding of a medium-frequency transformer.
  • Each secondary winding of this medium-frequency transformer is connected to a four-quadrant the outputs of which are the DC link DC voltage for supplying the converter-powered traction motors of the AC vehicle.
  • the high contact wire voltage is divided into several partial AC voltages by means of the four-quadrant actuators connected in series, which are then rectified and converted into an AC voltage of medium frequency, for example several kHz.
  • This alternating voltage of medium frequency is electrically isolated by means of the transformer and then converted into the already mentioned intermediate circuit direct voltage.
  • the several four-quadrant actuators connected in series with the capacitor bank on the output side, the several inverters and the medium-frequency transformer with several primary and secondary windings replace the mains transformer of the transformer-connected feed circuit described above. It can be seen that the known transformerless feed circuit leads to a negative assessment in terms of cost and reliability.
  • the object of the present invention is therefore to create a comparatively simple transformerless feed-in circuit for rail vehicles.
  • the transformerless feed circuit according to the invention is particularly simple in construction because the motor windings, for example a three-phase asynchronous machine or other machines, are each directly connected to a line-side converter of a plurality of converters connected in series on the output side.
  • the motor trains are thus at different potentials with respect to earth.
  • a transformer is therefore completely eliminated and not only increased in frequency, as with known solutions.
