P=UI,是輸出電壓和輸出電流的乘積。輸入電壓分交流輸入和直流輸入2種。輸出電壓一般是直流輸出，但也有交流輸出的。隔離電壓：隔離就是將輸出與輸入進(jìn)行電路上的分離。有以下幾個(gè)作用：一，電流變換；二，為了防止輸入輸出相互干擾；三，輸入輸出電路的信號(hào)特性相差太大，比如用弱信號(hào)控制強(qiáng)電的設(shè)備。封裝尺寸有插針，貼片的，和螺旋。輸出有單路輸出，雙路輸出及多路輸出。電源設(shè)計(jì)中即使是普通的直流到直流開(kāi)關(guān)轉(zhuǎn)換器的設(shè)計(jì)都會(huì)出現(xiàn)一系列問(wèn)題，尤其在大功率電源設(shè)計(jì)中更是如此。除功能性考慮以外，工程師必須保證設(shè)計(jì)的魯棒性，以符合成本目標(biāo)要求以及熱性能和空間限制，當(dāng)然同時(shí)還要保證設(shè)計(jì)的進(jìn)度。大功率電源模塊噪聲隔離：（模擬電路與數(shù)字電路隔離、強(qiáng)弱信號(hào)隔離）。天津大功率電源模塊采購(gòu)哪家好</p><p
