眾所周知：現(xian)代(dai)開關電源技術的發展(zhan)正(zheng)以(yi)沒有(you)過的規模改造著傳統的舊式電氣設備(bei)，廣(guang)泛進很大地節(jie)約了(le)電能(neng)、降低了(le)材耗與成本，明顯地減(jian)少了(le)電磁干擾。正(zheng)如現(xian)時(shi)在我們日常生活中流(liu)行的“變頻空(kong)調(diao)”、“節(jie)源40%以(yi)上的冰(bing)箱”、及工業常見的“弧焊(han)、電解、加熱、充電、超聲、電機調(diao)速”等等高技術附加值產品，正(zheng)就是使用(yong)了(le)高頻開關電源技術的結果！
我(wo)(wo)們現在(zai)(zai)來(lai)回顧一(yi)下：我(wo)(wo)們現代(dai)的(de)(de)(de)高(gao)(gao)頻大功(gong)率開(kai)關穩壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源技(ji)術，其實是(shi)一(yi)項知識面寬(kuan)、跨度大、難度大、又具有(you)風(feng)險的(de)(de)(de)復雜技(ji)術，它能把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網提供的(de)(de)(de)強電(dian)(dian)(dian)(dian)(dian)(dian)(dian)和(he)粗電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，變(bian)(bian)換成(cheng)各種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣設備和(he)儀器(qi)(qi)所(suo)需要的(de)(de)(de)高(gao)(gao)穩定度精(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)和(he)細(xi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，即提供不(bu)同(tong)規格的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流值，它是(shi)現代(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設備中重要的(de)(de)(de)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)。有(you)統(tong)計稱(cheng)：在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣設備中的(de)(de)(de)常見故障有(you)近(jin)一(yi)半(ban)出在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源問題上(shang)，我(wo)(wo)想這一(yi)點(dian)都不(bu)為過。因為現代(dai)高(gao)(gao)頻開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源所(suo)涉及(ji)(ji)的(de)(de)(de)內容橫跨了(le)多個學科(ke)，大概(gai)如微(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子精(jing)細(xi)加(jia)工(gong)的(de)(de)(de)智能化控制芯片(pian)系(xi)統(tong)，和(he)日益更(geng)新的(de)(de)(de)高(gao)(gao)性能功(gong)率電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力器(qi)(qi)件及(ji)(ji)高(gao)(gao)頻變(bian)(bian)壓(ya)器(qi)(qi)磁(ci)性材料，非晶(jing)和(he)微(wei)晶(jing)等(deng)等(deng)領域，正是(shi)如此，也(ye)就足以證明了(le)這項技(ji)術的(de)(de)(de)高(gao)(gao)科(ke)技(ji)含量的(de)(de)(de)價值，是(shi)一(yi)般企業可望而不(bu)可及(ji)(ji)的(de)(de)(de)。由于(yu)時(shi)間(jian)關系(xi)，在(zai)(zai)此也(ye)就不(bu)多作展開(kai)闡述(shu)了(le)。
