A control strategy for a conventional Lundell alternator and an active-rectifier using different modulation schemes was proposed in previous work. The modulation techniques examined indicated that the system could operate more efficiently than a passive rectifier over a certain speed and power range. This paper extends the modulation scheme analysis using a SVM scheme with six commutations per switching...
This paper presents a control strategy for a conventional Lundell alternator and an active-rectifier. The control scheme focuses on the minimisation of the stator copper losses of the alternator in an effort to maximise its efficiency. The modulation scheme of the active-rectifier is being investigated with the introduction of three different modulation techniques in order to quantify the effect they...
The losses in the electrical power generation system of a conventional internal combustion engine (ICE) vehicle is investigated. The system consists of a six-phase Lundell alternator and a six-phase passive rectifier. The losses of the alternator are measured using a test rig that simulates the ICE operation. It is shown that the Press-fit PN diodes currently in use in conventional alternator rectifiers...
