2. Generator Basics IEEE
Sep 27, 2016 · • The DC voltage appears in the main revolving field and induces a higher AC voltage in the main stator. • As the PMG rotor rotates, it produces AC voltage in the PMG stator. Circuit: Generator with a PMG • This voltage is sensed by the regulator, compared to a reference level, and output voltage is adjusted accordingly. • A three-phase AC
