Abstract

A rotating electrical machine, such as an aircraft starter-generator, that includes an exciter that has its stator windings supplied with electrical power from a power supply. One or more switches are electrically coupled between the exciter stator winding and the power supply and are configured and controlled so that a capacitance may be selectively placed electrically in series with the exciter stator windings.
