Diesel-electric locomotive

A method for supplying electrical power to a DC supply bus of a rotating electric motor of an electric vehicle is provided. The method includes the steps of selectively supplying electrical power to the bus via a first power supply at a first alternating voltage and selectively supplying electrical power to the bus via a second power supply at a second alternating voltage that is less than the first alternating voltage.

Method and system for supplying electrical power to a supply bus for an electric vehicle, recording medium, and vehicle for this method

This method maintains a direct voltage at the input of a DC/AC voltage converter in order to maintain an asynchronous motor in a magnetised state, the input of the converter being connected to a DC supply bus of an electric vehicle, and comprises, in a free wheel mode during which the vehicle coasts and the bus is disconnected from a catenary:
