A brushless capacitor excited alternator includes a rotor assembly having a coil and a diode connected in series with the coil. A stator contains the output coil of the alternator. Also wound on the stator are primary and auxiliary excitation coils. An excitation capacitor is provided with means for connecting it between various terminals on the primary and auxiliary excitation coils, and for connecting the two coils together. The magnetic field and thus the output voltage of the alternator may be varied by connecting the capacitor to different coil terminals.
