| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 90 === A switch-mode power supply for biochemical instruments is presented in this thesis. A cascade structure consisting of the buck converter and the half-bridge 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 half-bridge 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, a fixed current output and a fixed power output. Finally, the proposed functions are confirmed with the computer simulations and experimental results.
