A system and method is provided for starting a prime mover coupled to a synchronous starter/generator. The system includes an exciter converter that provides a non-fundamental only signal to a field winding of an exciter of the synchronous generator. The non-fundamental signal provides a first rotating field for the field winding of the exciter. Exciter armature windings induce an AC signal from the rotating field where at least one rectifier rectifies the induced AC signal. A field winding of a main machine provides a flux from the rectified signal of the at least one rectifier. Armature windings of the main machine receive an AC signal via a main machine converter.
