A system for controlling a propulsion system of a vehicle includes a switching system including a first switching device connecting a battery system to a first set of windings of an electric motor, and a second switching device connecting the battery system to a second set of windings. The system also includes a controller configured to transition the propulsion system from an initial propulsion mode in which an initial voltage is applied to the electric motor, to a target mode in which a target voltage is applied. The transitioning includes controlling the first switching device to provide current to the first set of windings at the initial voltage to produce torque, and subsequently controlling the second switching device to cause the battery system to apply the target voltage to the second set of windings while the current is provided to the first set of windings at the initial voltage.
