一、直流電子負載任務
電(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)(zai)用于測(ce)(ce)試直(zhi)流(liu)穩壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源、蓄電(dian)(dian)(dian)(dian)(dian)池等電(dian)(dian)(dian)(dian)(dian)源的(de)性能。設(she)計(ji)和(he)(he)制作一臺電(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)(zai)，有恒(heng)(heng)流(liu)和(he)(he)恒(heng)(heng)壓(ya)(ya)(ya)兩種模式(shi)，可(ke)手動切換。恒(heng)(heng)流(liu)方(fang)式(shi)時(shi)要求(qiu)不(bu)論(lun)輸(shu)入(ru)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)如何變(bian)化(hua)(hua)(hua)(在一定(ding)(ding)范(fan)圍內)，流(liu)過該電(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)(zai)的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)恒(heng)(heng)定(ding)(ding)，且電(dian)(dian)(dian)(dian)(dian)流(liu)值可(ke)設(she)定(ding)(ding)。工作于恒(heng)(heng)壓(ya)(ya)(ya)方(fang)式(shi)時(shi)，電(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)(zai)端電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)保持恒(heng)(heng)定(ding)(ding)，且可(ke)設(she)定(ding)(ding)，流(liu)入(ru)電(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)(zai)的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)隨被(bei)測(ce)(ce)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)源的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)變(bian)化(hua)(hua)(hua)而變(bian)化(hua)(hua)(hua)。圖中限流(liu)電(dian)(dian)(dian)(dian)(dian)阻取(qu)0.5Ω～1Ω，≥10W，以防電(dian)(dian)(dian)(dian)(dian)流(liu)過大損壞被(bei)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)路。被(bei)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)源使用橋(qiao)式(shi)整流(liu)和(he)(he)電(dian)(dian)(dian)(dian)(dian)容濾(lv)波(bo)構成，濾(lv)波(bo)電(dian)(dian)(dian)(dian)(dian)容容量總和(he)(he)不(bu)超過2200uF，以測(ce)(ce)量電(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)(zai)在應對含有脈(mo)動成分的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)信號時(shi)的(de)穩定(ding)(ding)性。
