Abstract

A starting/generating system operable in a starting mode and in a generating mode utilizes a dual permanent magnet generator (DPMG) having a motive power shaft and an armature winding together with a power converter having an input and an output. Relays are operable in the starting mode to connect the output of the power converter to the DPMG armature winding and are operable in the generating mode to connect the input of the power converter to the DPMG armature winding. The power converter is controlled in the starting mode such that the DPMG is operated as a motor to produce motive power at the motive power shaft and is controlled in the generating mode such that electrical power developed in the DPMG armature winding is converted into output power.
