style="text-indent:25px">工頻逆變器首先把直流電逆變成工頻低壓交流電；再通過工頻變壓器升壓成220V，50Hz的交流電供負載使用。它的優(yōu)點是結(jié)構(gòu)簡單，各種保護功能均可在較低電壓下實現(xiàn)。因其逆變電源與負載之間存有工頻變壓器，故逆變器運行穩(wěn)定、可靠、過負荷能力和抗沖擊能力強，且能夠壓制波形中的高次諧波成分。然而，工頻變壓器也存在笨重和價格高的問題，而且其效率也比較低。按目前水平制作的小型工頻逆變器，其額定負荷效率一般不超過90%，同時因工頻變壓器在滿負荷和輕負荷下運行時鐵損基本不變，因而使其在輕負荷下運行的空載損耗較大，效率也較低。高頻逆變器首先通過高頻DC/DC變換技術(shù)，將低壓直流電逆變?yōu)楦哳l低壓交流電；然后經(jīng)過高頻變壓器升壓后，再經(jīng)過高頻整流濾波電路整流成通常均在300V以上的高壓直流電；較后通過工頻逆變電路得到220V工頻交流電供負載使用。由于高頻逆變器采用的是體積小，重量輕的高頻磁芯材料，因而較大提高了電路的功率密度，從而使逆變電源的空載損耗很小，逆變效率得到提高，天津高頻逆變器銷售廠家。通常，天津高頻逆變器銷售廠家，天津高頻逆變器銷售廠家，用于中小型PVS中的高頻逆變器，其峰值轉(zhuǎn)換效率能達90%以上。正負極必須接對必須是逆變器正極接電瓶正極（紅），逆變器負極接電瓶負極（黑）。天津高頻逆變器銷售廠家</p><div

style="text-indent:25px">逆變器特點：1.轉(zhuǎn)換效率高、啟動快；2.安全性能好：產(chǎn)品具備短路、過載、過/欠電壓、超溫5種保護功能；3.物理性能良好：產(chǎn)品采用全鋁質(zhì)外殼，散熱性能好，表面硬氧化處理，耐摩擦性能好，并可抗一定外力的擠壓或碰擊；4.帶負載適應性與穩(wěn)定性強。工作效率：逆變器在工作時其本身也要消耗一部分電力，因此，它的輸入功率要大于它的輸出功率。逆變器的效率即是逆變器輸出功率與輸入功率之比，即逆變器效率為輸出功率比上輸入功率。如一臺逆變器輸入了100瓦的直流電，輸出了90瓦的交流電，那么，它的效率就是90%。使用范圍：1.使用辦公設(shè)備（如：電腦、傳真機、打印機、掃描儀等）；2.使用生活電器（如：DVD、音響、攝像機、電風扇、照明燈具等）；3.或需要給電池（手機、電動剃須刀、數(shù)碼相機、攝像機等電池）充電時；</p><p style="text-indent:25px">逆變器分類詳解：1、按逆變器輸出交流電能的頻率分，可分為工頻逆變器、中頻逆器和高頻逆變器。工頻逆變器的頻率為50～60Hz的逆變器;中頻逆變器的頻率一般為400Hz到十幾kHz;高頻逆變器的頻率一般為十幾kHz到MHz。2、按逆變器輸出的相數(shù)分，可分為單相逆變器、三相逆變器和多相逆變器。3、按照逆變器輸出電能的去向分，可分為有源逆變器和無源逆變器。凡將逆變器輸出的電能向工業(yè)電網(wǎng)輸送的逆變器，稱為有源逆變器;凡將逆變器輸出的電能輸向某種用電負載的逆變器稱為無源逆變器。4、按逆變器主電路的形式分，可分為單端式逆變器，推挽式逆變器、半橋式逆變器和全橋式逆變器。一定要選用金屬外殼產(chǎn)品：車載逆變器由于功率較大，發(fā)熱亦大。</p><div

style="text-indent:25px">正弦波逆變器與普通逆變器的區(qū)別是它輸出的波形是個完整的正弦波，失真率低，因此對收音機及通訊設(shè)備無干擾，噪聲也很低，保護功能齊全，整機效率高。而正弦波逆變器之所以能輸出完整的正弦波是因為采用了比PWM技術(shù)更先進的SPWM技術(shù)。SPWM原理基于脈沖作用于時間函數(shù)器件的等效原理：如果脈沖作用于時間函數(shù)器件，峰值與作用時間的乘積相等，可近似這些脈沖等效。SPWM基于固定頻率固定峰值（如開關(guān)頻率10k）的三角波與變頻變壓的參考正弦波（基波）進行比較，從而將直流電壓脈沖化（占空比變化的脈沖），以近似參考正弦波作用于器件上。調(diào)整參考正弦波的幅值和頻率，從而產(chǎn)生不同幅值和頻率的等效參考正弦波的直流電壓脈寬調(diào)制波。逆變器懷疑機器有故障時，請不要繼續(xù)進行操作和使用。成都12V逆變器價格</p><p

style="text-indent:25px">如何選用正確的ups電源逆變器：1、輸出電壓的不平衡度。在正常工作條件下，逆變器輸出的三相電壓不平衡度(逆序分量對正序分量之比)應不超過一個規(guī)定值，一般以%表示，如5%或8%。2、輸出電壓的波形失真度。當逆變器輸出電壓為正弦度時，應規(guī)定允許波形失真度(或諧波含量)。通常以輸出電壓的總波形失真度表示，其值不應超過5%(單相輸出允許10%)。3、額定輸出頻率。逆變器輸出交流電壓的頻率應是一個相對穩(wěn)定的值，通常為工頻50Hz。正常工作條件下其偏差應在±1%以內(nèi)。天津高頻逆變器銷售廠家</p></p><br
