The paper introduces a stator-PM, doubly salient; three phase alternator with flux linkage reversal (FRM),% in the stator phases concentrated coils. A diode rectifier and a single IGBT chopper are sized to form a 56 V dc output. The 14 V and 42 V loads are series connected with the car body as neutral point. Two additional IGBTs are used to cancel the neutral current when the load currents in the two power channels differ from each other. Configuration details, FEM field analysis results within a conceptual and then an optimization design and balanced and unbalanced load transients simulations for constant voltage control constitute the core of the paper. They suggest good power density, efficiency, load rejection capacity for speeds from 1800 rpm to 18 krpm, and from 1.5 kW to 3 kW power levels.
