Abstract:
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.
