| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 102 === This thesis presents the study and implementation of a single-stage semi-bridgeless SEPIC LED driver operated under continuous conduction mode (CCM). High efficiency and high power factor can be achieved with this topology. The semi-bridgeless configuration helps eliminate the conduction loss on the bridge rectifier. The operating principles are analyzed in detail. A 300-W prototype of the proposed LED driver has been built according to the design procedures. The experimental results are compared to those of a conventional counterpart with the same specifications to verify the feasibilities of the presented topology and control strategy.
