Amplidyne main exciter excitation system

The amplidyne exciter combines the basic characteristics of a conventional commutator-type exciter with the buckboost amplidyne features presently used for voltage regulators. The power required to control this exciter is small, permitting new types of voltage regulators to be used and additional, previously impossible exciter functions to be performed. Moreover, present functions are accomplished with greater ease, accuracy, and aggressiveness.
