Abstract
A power system includes an integrated drive generator (IDG) including an exciter field winding. A generator control unit (GCU) includes exciter drive circuit configured to electrically energize the exciter field winding, and a main stator configured to output voltage to at least one electrical load. The exciter drive circuit includes a dynamic flyback unit configured to selectively operate the exciter drive circuit between a first mode and a second mode different from the first mode based on a change in the at least one electrical load.
