ABSTRACT:
A control device for an electric train formed of plural coupled carriages each of which receive power from an overhead power line via a collector, wherein each carriage is provided with a power converter for converting power from the overhead line to a suitable level for a load within the respective carriage. Each carriage also includes an auxiliary power supply device having an input coupled to the output of the power converter of the another carriage and an output coupled to an input of the power converter of the same carriage, so that if the power level from the overhead line to one carriage falls below a predetermined value, the power converter of that carriage is supplied with power from the power converter of another carriage through the intermediary of the auxiliary power supply device of the same carriage.
