style="text-indent:25px">輸出電壓過低：針對電源模塊輸出參數(shù)異?！敵鲭妷哼^低。這可能會導(dǎo)致整體系統(tǒng)不能正常工作,如微控制器系統(tǒng)中,負(fù)載突然增大,會拉低微控制器供電電壓,容易造成復(fù)位。并且電源長時間工作在低輸入電壓情況下,電路的壽命也會出現(xiàn)極大的折損。因此輸出電壓偏低的問題是不容忽視的,那么輸出電壓過低通常是那些原因造成的呢?輸入電壓較低或功率不足;輸出線路過長或過細(xì),造成線損過大;輸入端的防反接二極管壓降過大;輸入濾波電感過大。針對這一類問題,可以通過調(diào)整供電或者更換相應(yīng)的外圍電路來改善,具體如下所示:調(diào)高電壓或換用更大功率輸入電源;調(diào)整布線,增大導(dǎo)線截面積或縮短導(dǎo)線長度,減小內(nèi)阻;換用導(dǎo)通壓降小的二極管;減小濾波電感值或降低電感的內(nèi)阻。
