Abstract

In this paper, a novel ac/dc interface with an integrated controller is proposed for the microscale wind power generation system (WPGS). The proposed interface is mainly composed of a dynamic maximum power point tracking (MPPT) control and a half-controlled single-stage rectifier with an integrated control. The half-controlled single-stage rectifier is proposed to replace the widely used two-stage converter for improving the current total harmonics distortion (THD) as well as the efficiency. The analytic expressions of the duty ratios for controlling the rectifier are also derived. Moreover, the dynamic response of the wind turbine and the extracted wind power are enhanced by the integrated dynamic MPPT control. Finally, from the experimental results, it can be seen that the current THD is reduced to around 5, and the total efficiency is increased by about 1215 depending on the wind speed variations.
