ABSTRACT:
An aircraft engine start system eliminates the need of a separate exciter field inverter by rearranging the exciter field windings and by utilizing external AC power. The aircraft engine is started by external AC power and once the engine has started, the engine can supply power back to a variable frequency AC bus as well as back to a constant frequency AC bus through the start/generator converter mode.
