Abstract:
A method of starting and operating a prime mover to improve power electronics utilization, said method comprising:controlling a kVA utilization plural phase inverter to provide a voltage signal to an armature winding of a starter/generator, said voltage signal having a terminal voltage Park vector and a current Park vector, said current Park vector comprising a q-axis and a d-axis current vector component; controlling said terminal voltage Park vector to adjust an angle value between said terminal voltage Park vector and said armature current Park vector, wherein said armature current is provided a d-axis current vector component to reduce a saturation level of said d-axis; and wherein at least a first angle value is provided by controlling said terminal voltage Park vector to be substantially in-phase with said current vector component of said armature current Park vector while reducing said saturation level of said d-axis to improve power electronics utilization provided by said starter/generator.
