Abstract:

This paper introduces a simple and practical topology for PMSM wind generation and analyzes relationship between variety of duty cycle of IGBT element in a DC/DC link and one of generator speed. A new method for adjusting variety of the duty cycle for maximum power point tracking is tested. The process of maximum power tracking is analyzed with a sample chart. Experimental results show validity of the analysis. 

Key words: maximum power point tracking, phase and amplitude control, duty cycle, permanent magnet synchronous generator
