style="text-indent:25px">電源模塊是一種PCB板上直插焊接式安裝的電源轉(zhuǎn)換裝置，采用了灌膠模塊化設(shè)計(jì)，在體積、散熱、可靠性方面具有很大的優(yōu)勢(shì)。一般acdc電源往往需要滿足一些安全距離，導(dǎo)致acdc部分電路面積較大。但是acdc電源模塊由于采用灌膠封裝，可以減小各元器件及布線之間的距離，有效了提高電源的功率密度，減少占用面積，縮小產(chǎn)品體積。電子產(chǎn)品趨向小型化發(fā)展，但是供電電源占據(jù)了很大一部分體積和重量，主要原因是電源中的變壓器、控制IC、MOS管、二極管、電容等是電路不可或缺的元器件。如果想把電源體積進(jìn)一步縮小或降低重量，只有采用新措施或新技術(shù)才能改變。acdc控制技術(shù)與傳統(tǒng)副邊反饋的光耦加結(jié)構(gòu)相比，其較大的優(yōu)勢(shì)在于省去了這兩個(gè)芯片以及與之配合工作的一組元器件，節(jié)省了系統(tǒng)板上的空間，在保證可靠性的基礎(chǔ)上且降低了電路成本。還有同步整流采用通態(tài)電阻極低的功率MOSFET取代整流二極管以降低整流損耗的新方案，MOS管的開通損耗會(huì)有效降低，同樣功率的電源MOSFET采用PCB散熱即可，而采用二極管整流方案還需要用到散熱片。目前開關(guān)電源在市場的主導(dǎo)下，日趨小型、輕量、高效、低成本、高可靠性等特點(diǎn)發(fā)展，為滿足市場和電子設(shè)備的要求，必須使用小型、輕量的電源方案。ACDC模塊電源是一種可直接安裝在印刷電路板上的電源。</p><div

變換器輸入為50/60Hz的交流電，因必須經(jīng)整流濾波，因此體積相對(duì)較大的濾波電容是必不可少的，同時(shí)因遇到安全標(biāo)準(zhǔn)及EMC指令的限制，交流輸入側(cè)必須加EMC率波電及使用符合安全標(biāo)準(zhǔn)的元件，這樣就限制AC/DC電源體積的小型化。另外，由于內(nèi)部的高頻、高壓、大電流開關(guān)動(dòng)作，使解決EMC電磁兼容問題難度加大，也就對(duì)內(nèi)部高密度安裝電路設(shè)計(jì)提出了很高的要求。由于同樣的原因，高電壓、大電流開關(guān)使很多電源損耗增大，限制了很高的要求。由于同樣的原因，高電壓、大電流開關(guān)使很多電源工作損耗增大，限制了AC/DC變換器模塊化的進(jìn)程，因此必須采用電源系統(tǒng)優(yōu)化方法，才能使其工作效率達(dá)到一定滿意程度。電源模塊可焊接和插入直接到電路板。嘉定區(qū)ACDC電源模塊哪家優(yōu)惠</p><p
