Apparatus for adjusting the terminal voltage of a single phase alternator employs a current sensor for sensing the load current. The load current signal is compared with a set point for producing an accelerator signal as the load changes. A drive for the alternator is controlled by an accelerator responsive to the accelerator signal. When the system is in a no load condition, the accelerator signal reduces the speed of the drive. A circuit responsive to the terminal voltage drives an exciter circuit to maintain the terminal voltage at not less than 50% of a desired or rated voltage.
