摘　　要：电力电子技术是UPS的核心,特别是直流-直流变换器在UPS中的运用最为常见。DC/DC变换器的电路种类较多,包括Boost电路、Buck电路、升降压斩波电路、Cuk电路及Zeta电路。其中Boost电路和Buck电路是最基本的,这两种电路的应用也最为广泛。在对各种直流斩波电路分析的基础上,本文采用专用芯片SC344B0X作为主控单元,利用Boost电路的工作原理设计了一款基于PC机5V电压侧的微型UPS。The power electronics technology is the core of UPS,especially DC/DC converter application is most common.DC/DC converters have more types of circuits,including Boost circuit,Buck circuit,Boost/Buck chopper circuit,Cuk circuit and Zeta circuit.Buck and Boost circuit are the most basic circuits and are used widely.On the base of the various DC chopper circuit analysis,SC344B0X is used as the main control unit,a PC-based5V voltage side of the micro-UPS is designed using the principle of Boost circuit.
