Outline of Final Research Achievements

This research proposes a new wind power generator system using a three-phase voltage-doubling rectifier which consists of only passive elements. Automatically, the three-phase voltage-doubling rectification circuit operates in double voltage mode in low wind velocity, and operates in bridge mode in high wind velocity. Therefore, the proposed generator system can obtain the maximum power output of wind turbines in a large velocity region without using the control circuit. The effectiveness of the proposed generator system was shown by simulations and experiments.
