| Abstract: | This paper introduces a simple and practical topology for PMSM wind generation and analyzes relationship between variety of the duty ratio of IGBT element in DC-DC link and one of generator speed. With that, a new method by adjusting variety of the duty ratio for maximum power point tracking is tried. The whole process of tracking maximum power is analyzed by sample chart and experiment is carried out. The results of experiment verify the analysis. |
