| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 93 === The various causes of the power loss in a switch-mode power supply are analyzed in this thesis. Several strategies for improving the power conversion efficiency are discussed and evaluated. Some comments providing considerations to reduce the power loss during implementation of a switching power supply are given. A high-efficiency switching power supply of 80-W (15V/5.34A) output power is implemented. L6561 and TEA1552 are adopted as the control IC’s for the power factor corrector (PFC) and the DC-to-DC converter, respectively. Soft switching capability is observed. The experimental results of the implemented power supply are satisfactory and confirmed to the theoretical analysis.
