| Summary: | 碩士 === 國立高雄應用科技大學 === 電機工程系 === 97 === This thesis is about the discussion and analysis of the operational principle for active power factor corrector (PFC) with discontinuous conduction mode (DCM). Meanwhile, a prototype of PFC with universal voltage input, high efficiency, and power factor close to 1 is designed, which comply with the United States Environmental Protection Agency's Energy Star 2.0 for the requirement of power factor on high power SMPS. Taguchi method is used for regulation the designing parameters to make further improvement, which can achieve the optimum design of PFC and then enhance the conversion efficiency of switching power supplies. The main contribution of this thesis is a high efficiency of active PFC has been realized and that concretely helps the energy-saving and carbon-reduction SMPS design.
