測(cè)試開(kāi)關(guān)電源采用專(zhuān)用示波器軟件更快

　　為了滿足效率和形式因素的要求，開(kāi)關(guān)模式電源制造商正在納入新的半導(dǎo)體和電路拓?fù)浣Y(jié)構(gòu)，同時(shí)也堅(jiān)持更高的電源完整性標(biāo)準(zhǔn)。因此，設(shè)計(jì)者必須作出更復(fù)雜的測(cè)量開(kāi)關(guān)模式波形，增加了測(cè)試時(shí)間，并增加了成本。

　　為了減少測(cè)試時(shí)間，測(cè)試設(shè)備制造商已經(jīng)開(kāi)發(fā)了硬件和軟件，共同實(shí)現(xiàn)自動(dòng)化的許多功能和復(fù)雜的分析。這種結(jié)合的一個(gè)很好的例子是功率分析儀軟件hdo4104 Teledyne LeCroy示波器。本文將介紹如何兩個(gè)可以用來(lái)進(jìn)行關(guān)鍵分析，以縮短電源的開(kāi)發(fā)和測(cè)試。

　　Efficiency， weight， and size drive innovative design and test approaches

　　Switched-mode power conversion， be it in power supplies， inverters， DC-DC converters， or motor controllers， offers the advantages of higher power efficiency and smaller size and weight for a given power level. However， these features have a cost in the form of greater complexity and higher component stress.

　　To address this， manufacturers are turning to new semiconductor types， a wider range of circuit topologies， and higher standards of power integrity. However， these demand detailed analysis of key characteristics such as：

　　Power losses

　　Safe operating area （SOA）

　　Control-loop margins

　　Line power integrity

　　Power supply performance
