“…Perreault [7], [8] has proposed a means for increasing the available output power from a conventional Lundell alternator by using a switched-mode rectifier to allow the alternator to operate at its maximum output power point over a wide range of speeds and yet still deliver a constant output voltage. Note that conventional alternators have high synchronous reactances and that the output voltage from the switched-mode rectifier in this case can be either higher or lower than the back-EMF voltage.…”

Abstract-This paper describes a high-power brushless interior permanent-magnet (PM) automotive alternator which does not use an inverter. The "inverterless" alternator is designed with a high back electromotive force voltage and high reactance, and acts as a constant current source over much of its wide constant power operating speed range. In this configuration, a switched-mode rectifier can be used to regulate the dc output voltage and current, which avoids the complexity and high cost of an inverter. An analysis of the modeling and performance of interior PM machines in this inverterless topology is described. Experimental results showing an outstanding constant power speed range are presented for a 6-kW concept demonstrator machine tested using a three-phase resistive load to simulate inverterless operation.

“…First, Lundell alternators feature a high stator inductance [10]. Considering that a typical alternator speed range spans between 2000 rpm and 15000-18000 rpm and the pole-pair number varies between 6 to 8 [1], it becomes evident that the synchronous reactance will be high, especially at high speed.…”

Abstract-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 have on the alternator's efficiency. Steady-state results from experimental measurements of the alternator rectifier system are compared against a standard passive rectifier. The comparison indicates that the modulation scheme of the active-rectifier is significant to the alternator's efficiency as well as to the overall system efficiency.

“…In [7], the current vector of an interior-type PMSG is controlled to optimize the wind-turbine operation at various wind speed, which requires six active switches to be controlled. Switch-mode rectifier has been investigated for use with automotive alternator with permanent-magnet synchronous machines [9], [10]. The switch-mode rectifier has also been investigated for small-scale variable-speed wind turbine [11], [12].…”

This paper presents a novel control strategy for the operation of a direct-drive permanent-magnet synchronous-generator-based stand-alone variable-speed wind turbine. The control strategy for the generatorside converter with maximum power extraction is presented. The stand-alone control is featured with output voltage and frequency controller that is capable of handling variable load. The potential excess of power is dissipated in the dump-load resistor with the chopper control, and the dc-link voltage is maintained. Dynamic representation of dc bus and small-signal analysis are presented. Simulation results show that the controllers can extract maximum power and regulate the voltage and frequency under varying wind and load conditions. The controller shows very good dynamic and steady-state performance. Disciplines Physical Sciences and Mathematics
