碩士 === 國立臺灣師範大學 === 應用電子科技學系 === 101 === The purpose of this thesis is to investigate efficiency and load transient response on three kinds of DC to DC buck converter topology. It's for getting the best efficiency of DC to DC buck converters for portable electronic products. Therefore, the concept of circuit design constitutes a low cost, low complexity and high efficiency system. Based on two circuit topologies which are ESR and RfCf, the proposed mixed circuit scheme is ESR+RfCf, also called hybrid. We derive the mathematical formula for DC to DC buck converter to analyze efficiency, and also use the simulation and experiments to prove analysis results. According to the analysis of all experimental results, the next step is to draw the conclusion and make the rule. As a result, designers understand disadvantages and advantages of three circuit topologies.
