摘要：隨著計(jì)算機(jī)性能的提高，使用計(jì)算機(jī)仿真方法幫助掌握電氣工程領(lǐng)域的基本知識(shí)并解決設(shè)計(jì)問(wèn)題是通行的方法。PSpice是一款功能強(qiáng)大的專(zhuān)用于電力電子電路的仿真軟件，可對(duì)各種模擬、數(shù)字電路進(jìn)行仿真，它的仿真波形與試驗(yàn)電路的測(cè)試結(jié)果十分相近。本文應(yīng)用PSpice對(duì)Boost變換器的全部工作過(guò)程進(jìn)行了仿真與分析，并對(duì)電路中儲(chǔ)能元件的各種工作狀態(tài)進(jìn)行了分析，給出了大量直觀的仿真波形，從而可以幫助科研人員或?qū)W習(xí)者加深對(duì)Boost變換器的理解。 敘詞：Boost變換器 PSpice 仿真 瞬態(tài)分析 Abstract：With the improvement of computer performance, Computer simulation technology becomes a usual method to help master the basic knowledge of power electronic system and to analyze and resolve the design or research problem. PSpice is a powerful general purpose analog circuit simulator that is used to verify analog or mixed digital circuit designs and to predict the circuit behavior. Its simulation waveforms is nearly as same as the experimental waveforms. The overall working stages of Boost converter is simulated and analyzed by PSpice. All the stages of stored energy elements of boost converter are also introduced. Some simulation waveforms are given to verify the analysis. Thus the understanding of boost converter is deepened.
