| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 92 === Abstract
A switch-mode power supply for biochemical instruments is presented in this thesis. A cascade structure consisting of the buck converter and the full-bridge phase-shifted PWM converter is used in the presented scheme, to provide the desired DC power for the biochemical instruments. To effectively restrain the inherent switching loss, the full-bridge phase-shifted converter is implemented by using zero voltage switching technique for a higher efficiency. The control circuit used in this paper can fulfill the functions of an adjustable voltage output. Finally, the proposed functions are confirmed with the computer simulations and experimental results.
