1. A method of operating a power system, comprising:
- running one or more of a plurality of generator units that each include a power source, a first electric generator, and a second electric generator;
supplying electricity from one or more of the first electric generators of the one or more running generator units to a first set of one or more electric power loads;
supplying electricity from one or more of the second electric generators of the one or more running generator units to a second set of one or more electric power loadswherein the power system is part of a mobile machine,wherein supplying electricity to the first set of one or more electric power loads includes supplying electricity to one or more electric propulsion motors to propel the mobile machine; and
wherein supplying electricity to the one or more electric propulsion motors to propel the mobile machine includes allowing the voltage of the electricity supplied to the one or more electric propulsion motors to vary dependent on the speed of the electric propulsion motors.

13. A mobile machine, comprising:
-
a first set of one or more electric power loads, including one or more electric propulsion motors for propelling the mobile machine; a second set of one or more electric power loads that is electrically isolated from the first set of one or more electric power loads; a plurality of generator units that each includes a power source, a first electric generator for supplying electricity to the first set of one or more electric power loads, and a second electric generator for supplying electricity to the second set of one or more electric power loads; and power-system controls that control one or more aspects of the supply of electricity from the plurality of generator units to the second set of one or more electric power loads, including, when one or more of the second electric generators are supplying electricity to the second set of electric power loads, regulating the voltage of the electricity supplied from the one or more second electric generators to the second set of one or more electric power loads. - View Dependent Claims (14, 15)
