A hybrid voltage regulator controls the voltage of three phases of alternating electricity produced by an alternator. A digital voltage regulator produces an average of the RMS voltage for each phase and produces an error value based on a ratio of the voltage to the frequency of the alternating electricity. The RMS voltage average and the error value are used to modify a voltage command designating a desired voltage level. The modified voltage command is processed by an analog voltage regulator that rectifies the alternator output voltage which then is averaged over an period of time. The resultant average voltage value is utilized to modify the voltage command to produce a regulated voltage command that determines a level of current to apply to excite the alternator.
