Control Strategy for a Multiphase Lundell-Alternator/Active-Rectifier System in 14V Automotive Power Systems

This paper presents a novel control strategy for a conventional six-phase Lundell alternator fed at the output with a MOSFET-based active rectifier. The signal references for the controller are calculated from a cost-function aiming to minimize the alternator stator copper losses in an effort to maximize the alternator-rectifier system overall efficiency. The system is initially simulated and tune...
