碩士 === 國立臺灣海洋大學 === 電機工程學系 === 102 === This paper mainly uses a computer simulation software LTspice and implemented circuit with the measured waveform as compared to verify the accuracy of the theoretical derivation. On the other hand, analysis and discussion on the passive power factor correction and active power factor correction technology, and the average current control technology and active power factor correction circuit design applied buck LED lighting, as a method to improve the power factor and efficiency. Finally, to achieve a high power factor and a high-efficiency LED lighting drivers and in accordance with design specifications and Current limits (Total Harmonic Distortion, THD) EN 61000-3-2, Class C specification.
