An electric drive system includes a first engine and a second engine. A
first electric generator is adapted to be driven by the first engine and
to generate a first output. A second electric generator is adapted to be
driven by the second engine and to generate a second output. An energy
storage device is adapted to receive the first output from the first
electric generator and the second output from the second electric
generator. An electric motor is operatively connected to the energy
storage device. The electric motor is operable to generate mechanical
power.
