它們顯然可以方便工程師，簡化系統(tǒng)的設(shè)計(jì)。但一般來說，它們只適用于較低的開關(guān)頻率，如300kHz或更低。此外，它們的功率密度通常沒有優(yōu)化，特別是與DC/DC芯片級(jí)模塊相比。電源模塊的隔離一般分為兩種：一種是輸入輸出的隔離。也就是說，輸入和輸出不是共本地的。另一種是輸出與輸出之間的隔離，相互隔離，互不干擾。電源管理模塊其實(shí)是隨著導(dǎo)體特別是半導(dǎo)體的工藝研究發(fā)展，封裝技術(shù)和高頻軟開關(guān)可以進(jìn)行分析大量的使用，電源系統(tǒng)模塊的規(guī)律密度越來越大，其轉(zhuǎn)換的效率問題也就導(dǎo)致越來越高。而應(yīng)用能力也就變得越來越簡單。使得學(xué)生電源變的更輕，更小，更薄，而且噪音也更低，其可靠性和抗干擾性也朝著更加高的方向不斷進(jìn)行社會(huì)發(fā)展。內(nèi)蒙古DCDC電源模塊廠一次電源的作用是將單相或三相交流電網(wǎng)變換成標(biāo)稱值為48V的直流電源。</p><div
