Power delivery system and method

A vehicle propulsion system comprising:

• an alternator configured to be disposed onboard a vehicle and to generate electric current based on mechanical energy received from an engine;
• a turbocharger operably coupled to the engine;
• a turbocharger assist device mechanically connected to the turbocharger and configured to generate electric current based on rotation of a rotor of the turbocharger;
• first and second traction motors mechanically connected to first and second wheelsets, respectively, each of the first and second wheelsets including at least two wheels, the first traction motor electrically isolated from the second traction motor;
• a first inverter electrically connected to the first traction motor and to the alternator via a primary bus, the first inverter configured to receive the electric current generated by the alternator to power the first traction motor to rotate the wheels of the first wheelset for propelling movement of the vehicle;
• and
• a second inverter electrically connected to the second traction motor and to the turbocharger assist device via a secondary bus, the second inverter configured to receive the electric current generated by the turbocharger assist device to power the second traction motor to rotate the wheels of the second wheelset for propelling the movement of the vehicle.
