摘要

Method for supplying a set of traction motors on board a vehicle, electronic power supply control device and associated set of traction motors Method for supplying a set (10) of traction motors comprising a first and a second traction motors (11, 12) and a first and a second inverter (21, 22), comprising the following steps: in a first mode, a first DC supply voltage being supplied at the input of said first and second inverters, supplying the first motor with the signal from the first inverter and supplying the second motor with the signal from the second inverter; in the second power supply mode, electrically disconnect the second motor from the second inverter, control the second inverter to operate as a rectifier; said second inverter being supplied by a second supply voltage; supplying the first inverter with the rectified voltage supplied by said second inverter operating as a rectifier and supplying the first motor with the AC signal delivered by the first inverter.
