Abstract
An electric powertrain for use with an engine and a traction device is disclosed. The electric powertrain has a DC motor/generator operable to receive at least a portion of a first mechanical output from the engine and produce a DC power output. The DC motor/generator is also operable to receive DC power and produce a second mechanical output. The electric powertrain further has a drivetrain operable to receive the DC power output and use the DC power output to drive the traction device. The drivetrain is also operable to generate DC power when the traction device is operated in a dynamic braking mode.
