A non-highway vehicle including an engine, a DC power source (Vdc) driven by the engine and providing DC power via a DC bus (42, 44), a traction motor (46), a circuit for connection to the DC bus (42, 44) for providing power to the traction motor (46), and a controller. The circuit includes at least two inverters (40x, 40y) which share the power supplied to the traction motor (46). A first inverter (40x) connects between the DC bus (42, 44) and the traction motor (46) and a second inverter (40y) connects between the DC bus (42, 44) and the traction motor (46). The second inverter (40y) is in parallel connection with the first inverter (40x.) The controller (Figs. 2, 5) coordinates operation of the first and second inverter.
L'invention porte sur un véhicule non adapté à l'autoroute comportant: un moteur; un générateur de courant c.c. entraîné par le moteur et distribuant le courant par l'intermédiaire d un bus c.c. (42, 44); un moteur électrique de traction; un circuit reliant le bus c.c. (42, 44) au moteur de traction (46) et un régulateur. Ledit circuit comporte au moins deux onduleurs (40x, 40y) qui partagent le courant d'alimentation du moteur de traction (46), un premier onduleur (40x) reliant le bus c.c. (42, 44) au moteur de traction (46) et un deuxième onduleur (40y), monté en parallèle avec le premier (40x), et reliant le bus c.c. (42, 44) au moteur de traction (46). Le régulateur coordonne le fonctionnement des deux onduleurs.
