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.
