in this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3d finite element modeling and experimental tests. the structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

The Brushless Doubly-Fed Reluctance Generator (BDFRG) is a potential alternative to the Doubly Fed Induction (DFIG) in wind power applications owing its reasonable cost, competitive performance, and high reliability. In comparison with (BDFIG), BDFRG more efficient easier control cage-less rotor. One of most preferable advantages over DFIG inherently better performance under unbalanced grid con...

Double-stator switched reluctance machines have higher torque density and lower vibration and acoustic noise level in comparison with conventional switched reluctance machines. Static characteristics of a 8/6 Double-stator switched reluctance machine have already calculated using finite element method. However, no measurement has been presented for the static torque of the machine. This paper p...

in this article our objective is to obtain steady state characteristics of shunt, series, and separately excited dc motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. we assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. it is ...

This paper presents a pumping system supplied by PV generator that is based on switched reluctance machine (SRM). Water systems are fundamental in many applications. Most of them can be used only during the day; therefore, they highly recommended for use with generators. For interface between panels and motor, new multilevel converter proposed. designed order to ensure fault-tolerant capability...

The Switched Reluctance Generator (SRG) has been widely studied for Wind Energy Conversion Systems (WECS). However, a major drawback of the SRG system adopting conventional control is slow response DC link voltage controller. In this paper, Proportional Resonant (PR) strategy proposed to output improve fast response. model high non-linearity, which makes design controllers difficult task. For r...
