Abstract
A powertrain includes a DC-DC converter, an electric machine, and a controller. The DC-DC converter may be configured to output a bus voltage. The controller may be configured to, in response to a torque request exceeding an available torque of the electric machine, command the converter to boost the bus voltage to a discrete step value selected from a predetermined number of available discrete step values, that changes in response to a selected operating mode of the powertrain changing, to increase the available torque.
