Performances of a hybrid excited flux-switching DC-alternator: Analysis and experiments

In this paper, a finite elements analysis and experimental results of a hybrid excited flux switching 3kW DC-alternator are presented. The studied machine is presented and its flux control capability is calculated. The short-circuit current is explored by mean of two different methods. One of them cancels all harmonic components of the flux. The second part presents the alternator connected to a diode bridge rectifier with a DC controlled bus. The performances of the studied machine are evaluated by the model and compared to experimental results. Finally, we compared the experimental performance of the studied machine with NdFeB magnets, ferrite magnets and without magnet.
