基于Matlab的高功率因數校正技術的仿真研究

摘要：本論文闡述了功率因數校正意義和必要性，以及分析了模擬控制器和數字控制器在單相Boost PFC變換器中應用，同時給出了它們的Matlab仿真結果，論證了數字控制器在PFC中的可行性。除此之外，我們并且對模擬控制器和數字控制器在Boost PFC電路中的實驗結果進行了比較，最后論證了數字控制器會取代模擬控制器，成為PFC中主要控制方式。 敘詞：功率因數校正；模擬控制器；數字控制器； TMS320LF2407 Abstract： The paper expounds the significance and necessity of PFC. We also analyses the application of analog controller and digital controller in single Boost PFC converter. At the same time, we give the simulated results in Matlab and prove the feasibility of digital controller in Boost PFC converter. Besides we carry out comparison on the experimental effects of analog controller and digital controller in PFC. At last we demonstrate that digital controller will take place of analog controller and become the main control mode of PFC in the future.
