Title (EN) METHOD AND SYSTEM FOR POWERING A VEHICLE
(FR) PROCÉDÉ ET SYSTÈME DE PULSION D'UN VÉHICULE
Abstract: front page image
(EN) A system for powering a vehicle includes a traction bus, an auxiliary bus, chopper devices, and a control unit. The traction bus is coupled with traction motors of the vehicle to supply a first voltage to power the traction motors. The auxiliary bus is coupled with non-traction motors of the vehicle to supply a different, second voltage to the non-traction motors to. The chopper devices are conductively coupled with both the traction bus and the auxiliary bus to control conduction of the first voltage on the traction bus to the auxiliary bus as the second voltage using first and second duty cycles. The control unit is coupled with the chopper devices to control the first and second duty cycles of the chopper devices, respectively, such that the first voltage on the traction bus is changed (e.g., reduced) to the second voltage on the auxiliary bus.
(FR) La présente invention concerne un système de propulsion d'un véhicule comprenant un bus de traction, un bus auxiliaire, des dispositifs hacheurs et une unité de commande. Le bus de traction est raccordé aux moteurs de traction du véhicule pour fournir une première tension pour propulser les moteurs de traction. Le bus auxiliaire est raccordé aux moteurs de non-traction du véhicule pour fournir une seconde tension différente aux moteurs de non-traction. Les dispositifs hacheurs sont raccordés de manière conductrice au bus de traction et au bus auxiliaire pour commander la conduction de la première tension sur le bus de traction jusqu'au bus auxiliaire, la seconde tension utilisant des premier et second cycles de service. L'unité de commande est raccordée aux dispositifs hacheurs pour commander les premier et second cycles de service des dispositifs hacheurs, respectivement, de sorte que la première tension sur le bus de traction est modifiée (par ex., réduite) par rapport à la seconde tension sur le bus auxiliaire.
