Abstract:
1. An electric powertrain for use with an engine and a traction device, comprising: a DC motor/generator operable to: a drivetrain operable to: an AC alternator operable to receive a portion of the first mechanical output and produce an AC power output; and a rectifier coupled with the AC alternator, the rectifier being operable to convert the AC power output to a DC power output combinable with the DC power output of the DC motor/generator, wherein: the engine is rated to produce a first amount of mechanical power and to receive a second amount of mechanical power, the second amount of mechanical power being less than the first amount of mechanical power; the DC motor/generator is sized based on the second amount of mechanical power; and the AC alternator is sized based on a difference between the first and second amounts of mechanical power.
