在我們日常生活中隨處可見，其體積小重量輕,便于攜帶,效率高,損耗小等優勢得到了人們的肯定。 開關電源的設計需要滿足相關的電性要求和相關的技術型指標以及參數,開關電源適配器的性能指標可分為AC輸入,DC輸出,電路保護功能,系統功能,電氣絕緣和電磁兼容等方面,有些甚至還有顯示和指示功能。接下來就為大家介紹一下開關電源的技術指標要求。

開關電源適配器電氣性能指(zhi)標要求：

　AC輸入電(dian)(dian)性要求一般開關電(dian)(dian)源(yuan)適配器的(de)輸入電(dian)(dian)壓(ya)范圍(wei):AC 100～240V AC 電(dian)(dian)壓(ya)調整范圍(wei):90～264V AC 輸入電(dian)(dian)壓(ya)頻(pin)率(lv):50～60Hz 頻(pin)率(lv)調整范圍(wei):47～63Hz,

　DC輸(shu)出(chu)(chu)電(dian)(dian)(dian)性要求有額定輸(shu)出(chu)(chu)電(dian)(dian)(dian)壓(ya)(V)和(he)電(dian)(dian)(dian)流(A),輸(shu)出(chu)(chu)電(dian)(dian)(dian)壓(ya)調整(zheng)率為輸(shu)出(chu)(chu)電(dian)(dian)(dian)壓(ya)的5%,穩(wen)壓(ya)精度也就(jiu)是(shi)電(dian)(dian)(dian)壓(ya)調整(zheng)率和(he)負載(zai)調整(zheng)率,瞬態響應(ying),輸(shu)出(chu)(chu)紋(wen)波(bo)(bo)電(dian)(dian)(dian)壓(ya)及紋(wen)波(bo)(bo)電(dian)(dian)(dian)流,紋(wen)波(bo)(bo)及噪音(mVp-p)一般

　電(dian)(dian)氣(qi)絕(jue)緣部分(fen),開關電(dian)(dian)源適配(pei)器的(de)(de)電(dian)(dian)氣(qi)絕(jue)緣是安全指標中(zhong)的(de)(de)重要內容,出(chu)廠(chang)的(de)(de)開關電(dian)(dian)源必須經過電(dian)(dian)氣(qi)絕(jue)緣試驗,才能夠投(tou)入市場(chang)使用,交流(liu)輸(shu)(shu)入端對直流(liu)輸(shu)(shu)出(chu)端的(de)(de)電(dian)(dian)氣(qi)絕(jue)緣測試,漏電(dian)(dian)流(liu)測試
