| Abstract |
Recently, the switched reluctance generator (SRG) is emerging to complement the shortcomings of PM machine in renewable energy applications because of its advantages. However, the SRG have fundamental disadvantages such as vibration and noise due to the pulse-driven operation and the reluctance torque variation. This paper is focused on overcoming the disadvantages of the SRG; the rotor geometry is proposed to reduce the torque pulsation and it is designed considering the variation of inductance when the SRG is operated in a generating mode. As a result, it is available to reduce the effect of the torque ripple and vibration. In order to verify the effectiveness, the analysis result of SRG with the proposed rotor structure is compared with a conventional rotor structure under the same specifications and stator dimension. Each model is built as prototypes and the experimental verification is conducted as a result. |
