EXCITER DRIVE CIRCUIT INCLUDING OCNFIGURABLE FLYBACK UNIT WITH FAST ENERGY FIELD COLLAPSE

摘要

A power system includes an integrated drive generator, IDG, (104) including an exciter field winding (116). A generator control unit, GCU, (102) includes exciter drive circuit (111) configured to electrically energize the exciter field winding, and a main stator (108) 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.
