A power generator in which the rotor's mechanical rotation speed and the output frequency can be varied substantially independently of each other through electronic controls, to achieve results such as better match between speed and load regime of the primary mover and the generator's output.

1. An alternating current generator comprising:a rotor having DC-wound rotor field coils connected to respective commutator terminals, said rotor being mounted for rotation at a mechanical speed; a stator electromagnetically coupled with said rotor and having at least one stator winding and an output for AC power; an electronic commutator circuit rotating with said rotor to deliver coil energizing power to said rotor coils to thereby create a rotor field rotating at a field speed; and a control circuit coupled to said electronic commutator circuit to control at least a timing of said energizing power to thereby cause a selected speed relationship between said mechanical speed and field speed for a selected frequency of said AC power.
