An alternator generates output power at two or more independent voltages. The alternator has two independent output windings configured to generate the power needed for each output. Each output voltage is sensed by a regulator that controls switching rectifiers to supply the current needed to satisfy the electric power demand of the loads connected to each output. After both output load demands are satisfied, the regulator switches off the alternator field. When power demand from either load rises, the alternator field is switched on along with the respective switching rectifier to satisfy the power demand. The output voltage grounds and control signals may be electrically isolated from each other.

1. A method for regulating an electrical generator comprising a field source and first and second power generating windings to supply current at first and second outputs, respectively, said method comprising:(a) conducting current between the first power generating winding and the first output when the first output voltage falls below a first threshold; (b) conducting current between the second power generating winding and the second output when the second output voltage falls below a second threshold; and (c) increasing current through the field source when either one of the first and second output voltages falls below the respective threshold.
