An electric drive system has a power source and a generator operatively
connected to the power source. The generator is configured to produce a
power output. The electric drive system also has at least one capacitor
configured to store a supply of power. The electric drive system further
has a common bus configured to direct the power output to the capacitor.
The electric drive system also has at least one motor configured to
receive power from the common bus. The electric drive system additionally
has a controller in communication with the at least one motor and the
generator. The controller is configured to receive at least one input
associated with the motor, to determine a requested motor power as a
function of the at least one input, and to operate the generator to
produce the requested motor power.
