In this chapter, an overview of multiphase electric machines is discussed. Alternating and rectified DC output voltage waveforms of three- and nine-phase HPM generators with an associated power electronics rectification stage are presented. Comparison of three- and two nine-phase machine winding schemes in terms of winding factor is studied. Two nine-phase HPM generators with different numbers of stator turns are compared for their terminal and DC-link output power and the quality of the generated DC output voltage. In addition, sensitivity analysis based on machine synchronous inductance for three- and nine-phase configurations with varying load conditions are performed. Finally, a loss comparison between the HPM and PM machines and their rectification systems for three- and nine-phase winding configurations is presented.
