碩士 === 國立雲林科技大學 === 電機工程系碩士班 === 100 === This thesis focuses on power factor correction in the application of industry. We employ the full-bridge rectifier circuit which is most used in industry to discuss power factor. We are going to analyze in depth with the operation of filter capacitor and find out how it affects the circuit. By summing up merits and demerits with the traditional way, we propose a novel power factor correction method. In our method, the IC produced by the famous company PI is chosen to be the core of the correction circuit. We combine the traditional architecture with the chosen IC to accomplish a better correction circuit. The proposed circuit is analyzed by using Orcad Pspice which is developed by Cadence. The simulation results show that the power factor of our method reaches 0.99.
