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 tuned in MATLAB/Simulink and then experimentally verified. The steady-state efficiency results from experimental measurements of the alternator/rectifier system are compared against a standard passive rectifier. The results indicate a better overall efficiency compared to the passive rectifier, for an alternator speed of up to approximately 5000 rpm, corresponding to city driving.
