紋波電壓的幾個(gè)政策方法。
1． 最大紋波電壓。
在額外輸出電壓和負(fù)載電流下，輸出電壓的紋波（包括噪聲）的必定值的大小，通常以峰峰值或有用值標(biāo)明。
2． 紋波系數(shù)Y（%）。
在額外負(fù)載電流下，輸出紋波電壓的有用值Urms與輸出直流電壓Uo之比，既
y=Umrs/Uo x100%
3． 紋波電壓克制比。
在規(guī)矩的紋波頻率（例如50HZ）下，輸出電壓中的紋波電壓Ui~與輸出電壓中的紋波電壓Uo~之比，即：
紋波電壓克制比=Ui~/Uo~ 。
選用變頻器工作時(shí)，電機(jī)的起動(dòng)電流、起動(dòng)轉(zhuǎn)矩怎么？
選用變頻器工作，隨著電機(jī)的加快相應(yīng)跋涉頻率和電壓，起動(dòng)電流被束縛在150%額外電流以下(根據(jù)機(jī)種不一樣，為125%~200%)。用工頻電源直接起動(dòng)時(shí)，起動(dòng)電流為6~7倍，因而，將發(fā)作機(jī)械電氣上的沖擊。選用變頻器傳動(dòng)可以滑潤(rùn)地起動(dòng)(起動(dòng)時(shí)間變長(zhǎng))。起動(dòng)電流為額外電流的1.2~1.5倍，起動(dòng)轉(zhuǎn)矩為70%~120%額外轉(zhuǎn)矩；對(duì)於帶有轉(zhuǎn)矩主動(dòng)增強(qiáng)功用的變頻器，起動(dòng)轉(zhuǎn)矩為100%以上，可以帶全負(fù)載起動(dòng)。
過(guò)熱維護(hù)。在電源內(nèi)部發(fā)作失�；蛞蜻\(yùn)用不當(dāng)而使電源溫升超支時(shí)間斷電源的工作并宣布報(bào)警信號(hào)。九． 溫度漂移和溫度系數(shù)。
