就和其它傳統(tǒng)行業(yè)一樣，UPS行業(yè)也遇到了競爭加劇和產(chǎn)業(yè)升級(jí)的壓力：產(chǎn)品功能同質(zhì)化嚴(yán)重，各種山寨劣質(zhì)產(chǎn)品層出不窮，為了追求市場，不斷壓低產(chǎn)品銷售價(jià)格，而為了尋求利潤空間，就不得不控制成本，偷工減料，降低產(chǎn)品質(zhì)量。這種惡性競爭的后果就是忽視了客戶的需求，**終的結(jié)果還是傷害整個(gè)行業(yè)。<span

走線阻抗大。電源模塊輸出與負(fù)載連接必然要有一段PCB走線，走線越長、走線越窄則它的等效電阻越大。等效電阻可以認(rèn)為是串聯(lián)在負(fù)載的工作回路中，將起到分壓作用，因此導(dǎo)致負(fù)載兩端的電壓小于模塊的輸出電壓。此外，除了走線問題還有很多情況起到類似的作用，比如焊點(diǎn)接觸不良導(dǎo)致等效電阻增加，線路氧化或腐蝕導(dǎo)致等效電阻增加。<span style="font-size:12px;">防反接二極管。很多產(chǎn)品的AC和DC部分是不在一塊板上的，在生產(chǎn)或終端客戶使用中不可避免涉及到插拔電源連接器的情況。為防止此過程中的反接導(dǎo)致的硬件損壞，常串入一只二極管解決。以壓降0.7V的二極管為例，b1 b2間的電壓將比a1 a2間電壓小0.7V，這也就是上面所討論的輸入電壓偏低的情況，可以通過選擇壓降低的管子或者直接提高a1 a1間電壓的方法解決。</span> </p> <p> 上海深圳天磁科技有限公司電-源方案</p><p
