在晶體管大慶購買的愛立信電源測(cè)試(愛立信電源是全橋軟開關(guān)電路...還有通信電源哦4800W
周末回去測(cè)試了一下愛立信通信電源,質(zhì)量確實(shí)大大的好,重量大概6斤,無風(fēng)扇設(shè)計(jì),功率因數(shù)校正用到的是L4981,主電源部分用的是UC2875,主變壓器用的是EE55,飛利浦3F3磁芯,查資料稱頻率可以用到200KHZ-1MHZ,確實(shí)很厲害,高頻損耗小.這次測(cè)試了一下,空載27.2W,發(fā)現(xiàn)空載通電2個(gè)小時(shí),外殼很熱,磁芯也很熱,主開關(guān)管那邊也很燙,空載功率因數(shù)只有0.4 ,通過接一逆變器(24V-220V)帶2個(gè)200W的燈泡功率因數(shù)達(dá)到0.98,帶載感覺并沒有空載那么熱,是全橋電路,下面多圖,測(cè)試很辛苦,如果覺得好希望大家頂頂
全部回復(fù)(51)

較肯定的應(yīng)不是LLC,也很有可能是不對(duì)稱半橋
我覺得應(yīng)該不是LLC,我仔細(xì)看了艾默生的那款,個(gè)人猜測(cè)應(yīng)該是基于UC2875控制的ZVS移相全橋,變壓器原邊加諧振電感.所以帶來的問題是空載或輕載情況下效率低,帶負(fù)載效率會(huì)提高.
艾默生的那款和愛立信的那款原理基本上一樣,部分元件用料不一樣,布局不一樣.如,愛立信的磁芯用飛利浦的3F3EE55磁芯,艾默生用EE42,愛立信的輸出電感用兩個(gè)磁環(huán)并聯(lián)使用,而艾默生只用一個(gè)磁環(huán),愛立信用三塊板,艾默生只有一塊,愛立信后面板上有11個(gè)器件,艾默生只有8個(gè)(4個(gè)IRF840,以此推測(cè)應(yīng)該為全橋拓?fù)?,不知道二者開關(guān)頻率如何,待測(cè)試.總體感覺艾默生那款就是愛立信降成本型號(hào).
從電路板的標(biāo)簽來看,愛立信應(yīng)該是98年產(chǎn),而艾默生應(yīng)該是2003年產(chǎn),二者時(shí)間相差5年.
絕緣材料,愛立信用的是白色的,比較厚實(shí),艾默生用的粉紅色,厚度較薄
二者標(biāo)稱完全一樣,目前不敢斷定其性能孰優(yōu)孰劣,但僅從硬件成本上來看,愛立信的成本明顯要高于艾默生.

我覺得應(yīng)該不是LLC,我仔細(xì)看了艾默生的那款,個(gè)人猜測(cè)應(yīng)該是基于UC2875控制的ZVS移相全橋,變壓器原邊加諧振電感.所以帶來的問題是空載或輕載情況下效率低,帶負(fù)載效率會(huì)提高.艾默生的那款和愛立信的那款原理基本上一樣,部分元件用料不一樣,布局不一樣.如,愛立信的磁芯用飛利浦的3F3EE55磁芯,艾默生用EE42,愛立信的輸出電感用兩個(gè)磁環(huán)并聯(lián)使用,而艾默生只用一個(gè)磁環(huán),愛立信用三塊板,艾默生只有一塊,愛立信后面板上有11個(gè)器件,艾默生只有8個(gè)(4個(gè)IRF840,以此推測(cè)應(yīng)該為全橋拓?fù)?,不知道二者開關(guān)頻率如何,待測(cè)試.總體感覺艾默生那款就是愛立信降成本型號(hào).從電路板的標(biāo)簽來看,愛立信應(yīng)該是98年產(chǎn),而艾默生應(yīng)該是2003年產(chǎn),二者時(shí)間相差5年.絕緣材料,愛立信用的是白色的,比較厚實(shí),艾默生用的粉紅色,厚度較薄二者標(biāo)稱完全一樣,目前不敢斷定其性能孰優(yōu)孰劣,但僅從硬件成本上來看,愛立信的成本明顯要高于艾默生.
我把卡子拆下來看過 只有3個(gè)840,難道看錯(cuò)了!這個(gè)星期回去再檢查一下!!!再來匯報(bào)

您好,能拍張清晰點(diǎn)的控制板發(fā)來看看嗎?我想研究下,無耐晚了步,大慶的機(jī)器都賣完了我郵箱yujiao106@live.cn
芬蘭的高效率充電器!功率部分很另類! 超寬電壓輸入
