ABSTRACT:
A circuit and a method for controlling excitation current to the field winding of a generator or motor. An uncontrolled current source supplies sufficient excitation current to maintain the generator output voltage at a level slightly below the seated voltage when no load is present. A controlled current source compensates for generator loading to supply additional excitation current sufficient to raise the output voltage to approximately the rated voltage.
