Optimum Pole Arc Offset in Permanent Magnet Synchronous Generators for Obtaining Least Voltage Harmonics %K Synchronous generator %K pole arc offset %K surface mounted %K voltage wave-shape %K THD %R 10.24200/sci.2017.4357 %X In this study the effect of parametric variatıon of the pole-arc offset distance on the performance of a permanent-magnet synchronous generator (PMSG) used in wind energy applications has been investigated. Fourier analyses of the voltage wave-shapes that are obtained by the parametric variation of the pole-arc offset value have been made. The THD is determined for each voltage wave-shape. As a result of optimization study the efficiency and the output power have been kept approximately constant. The THD of the output voltage has been decreased %U https://scientiairanica.sharif.edu/article_4357_0a52fae70b4a160cd3bdf0dcd2f3d10c.pdf
