Abstract
A method and apparatus for supplying electrical power in an earth moving machine is provided. The method and apparatus includes an engine adapted to deliver primary power at a variable speed to the earth moving machine. A hydraulic system is connected to and driven by the engine. The hydraulic system in turn is connected to and drives a work implement. A variable input speed, constant output generator system is connected to and driven by the engine at a variable speed. The generator delivers electrical power at a constant value independent of variations of the speed of the engine. There is at least one auxiliary system adapted to receive the electrical power.
