style="text-indent:25px">如何選用正確的ups電源逆變器：1、保護(hù)。過電壓保護(hù)：對于沒電壓穩(wěn)定措施的逆變器，廣州小型逆變器銷售廠家，應(yīng)有輸出過電壓防護(hù)措施，以使負(fù)截免受輸出過電壓的損害。過電流保護(hù)：逆變器的過電流保護(hù)，應(yīng)能保證在負(fù)載發(fā)生短路或電流超過允許值時及時動作，使其免受浪涌電流的損傷。3、起動特性。表征逆變器帶負(fù)載起動的能力和動態(tài)工作時的性能。逆變器應(yīng)保證在額定負(fù)載下可靠起動。4、噪聲。電力電子設(shè)備中的變壓器、濾波電感、電磁開關(guān)及風(fēng)扇等部件均會產(chǎn)生噪聲。逆變器正常運(yùn)行時，其噪聲應(yīng)不超過80dB，廣州小型逆變器銷售廠家，小型逆變器的噪聲應(yīng)不超過65dB，廣州小型逆變器銷售廠家。在整體外觀而言，它也是非常漂亮的。廣州小型逆變器銷售廠家</p><div

style="text-indent:25px">逆變器的特點(diǎn)：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(hù)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(fù)載適應(yīng)性與穩(wěn)定性強(qiáng)。逆變器的工作效率：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%。廣州小型逆變器銷售廠家一般與整個系統(tǒng)融為一體，但是又需要突出，因為他的作用非常重要。</p><div

style="text-indent:25px">按輸出波形劃分，逆變器分為幾類？主要分兩類，正弦波逆變器和方波逆變器。正弦波逆變器輸出的是同我們?nèi)粘Ｊ褂玫碾娋W(wǎng)一樣甚至更好的正弦波交流電，因為它不存在電磁污染。方波逆變器輸出的則是質(zhì)量較差的方波交流電，其正向較大值到負(fù)向較大值幾乎在同時產(chǎn)生，這樣，對負(fù)載和逆變器本身造成劇烈的不穩(wěn)定影響。特別是負(fù)載能力差，*為額定負(fù)載的40－60％。如所帶的負(fù)載過大，方波電流中包含的三次諧波成分將使流入負(fù)載中的容性電流增大，嚴(yán)重時會損壞負(fù)載的電源濾波電容。應(yīng)對這些缺點(diǎn)，出現(xiàn)了準(zhǔn)正弦波也叫改良正弦波、修正正弦波、模擬正弦波逆變器，其輸出波形從正向較大值到負(fù)向較大值之間有一個時間間隔，使用效果有所改善，但準(zhǔn)正弦波的波形還是由折線組成，屬于方波范疇，連續(xù)性不好。總的來說，正弦波逆變器提供高質(zhì)量的交流電，能夠帶動任何種類的負(fù)載，但技術(shù)要求和成本也高。準(zhǔn)正弦波逆變器可以滿足我們大部分的用電需求，效率高，噪音小，售價便宜，是市場中的主流產(chǎn)品。</p><p style="text-indent:25px">逆變器輸入接口部分：輸入部分有3個信號，12V直流輸入VIN、工作使能電壓ENB及Panel電流控制信號DIM。VIN由Adapter提供，ENB電壓由主板上的MCU提供，其值為0或3V，當(dāng)ENB=0時，逆變器不工作，而ENB=3V時，逆變器處于正常工作狀態(tài)。而DIM電壓由主板提供，其變化范圍在0～5V之間，將不同的DIM值反饋給PWM控制器反饋端，逆變器向負(fù)載提供的電流也將不同，DIM值越小，逆變器輸出的電流就越大。電壓啟動回路：ENB為高電平時，輸出高壓去點(diǎn)亮Panel的背光燈燈管。如果內(nèi)部熱量不能及時散出，輕則影響元器件壽命，重則有產(chǎn)生火災(zāi)的危險。</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(jī)及通訊設(shè)備無干擾，噪聲也很低，保護(hù)功能齊全，整機(jī)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(jìn)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(jìn)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。使得直流電壓對電感進(jìn)行充放電，這樣電感的另一端就能得到交流電壓。青島三相雙向逆變器廠家推薦</p><p

style="text-indent:25px">逆變器小知識：我們看一下修正弦波逆變器應(yīng)用于電視機(jī)的情況。電視機(jī)對逆變器有以下三條要求：首先，電視機(jī)在開機(jī)時，消磁電路對電能有極大的瞬間需求，因此對逆變器的峰值功率要求很高。一臺29英寸數(shù)字彩電，正常工作狀態(tài)下的功耗約為80瓦，而開機(jī)的瞬間功率高達(dá)1450瓦。其次，因為電視機(jī)的場頻等于交流電網(wǎng)頻率，逆變器輸出交流電的頻率必須準(zhǔn)確。第三，逆變器不應(yīng)對電視機(jī)產(chǎn)生干擾。即使能滿足以上三個條件，電視機(jī)在使用準(zhǔn)正弦波交流電時，畫面仍會有幾條固定的干擾紋，色彩也會輕微偏綠。廣州小型逆變器銷售廠家</p></p><br
