POWER DISTRIBUTION SYSTEM FOR RAILBOUND VEHICLES USING POWER ELECTRONIC TRACTION CONVERTER UNITS AND A SWITCHING MODULE

The present invention relates to a power distribution system for a railbound vehicle, comprising a switching module (12), a DC distribution bus (3) included in a DC power path and a power electronic traction converter unit (13) for receiving AC power via the one or more AC power paths which is configured to convert the received AC power to DC power which is applied to the DC distribution bus (3), wherein the switching unit comprising an input terminal for receiving power from an external power supply, reconfiguration switches (24, 25) configured either to direct DC power of the external power supply received via the input terminal to the DC power path or to direct AC power of the external power supply received via the input terminal to a respective one of one or more AC power paths and an adaptation element (20) for providing AC and DC filtering of the power received via the input terminal.
