Abstract:
A vehicle propulsion system includes a first bi-directional DC-DC converter coupled to a first DC bus, an energy storage system comprising at least one energy storage unit coupled to the first bi-directional DC-DC converter, a first DC-to-AC inverter coupled to the first DC bus, and a first electromechanical device coupled to the first DC-to-AC inverter. A controller is programmed to determine a real-time operating speed of the first electromechanical device, compare the real-time operating speed of the first electromechanical device to a scheduled speed of the first electromechanical device, and selectively control the first bi-directional DC-DC converter to shift a voltage of the first DC bus based on the comparison.
