| Summary: | 碩士 === 國立雲林科技大學 === 電機工程系碩士班 === 91 === This thesis presents a DSP-based fully digital-controlled single-phase power factor converter (PFC). The proposed PFC controller consists of an inner current-loop controller and an outer voltage-loop controller. The current-loop controller adopts hysteresis current control to achieve power factor correction. The voltage-loop controller employs a PI controller to achieve output voltage regulation. This paper adopts TMS320F240 digital signal processor (DSP) as the controller to achieve high power factor, low steady-state error, output voltage regulation, phase- locked loop and parallel operation. Finally, an experimental test was carried out on a 500 W PFC converter using DSP controller and the experimental results verify the feasibility and superiority of the proposed digital AC/DC converter.
