<p><span style="font-size: 14px"> 高頻變壓器是作為開關(guān)電源最主要的組成部分。開關(guān)電源一般采用半橋式功率轉(zhuǎn)換電路，工作時兩個開關(guān)三極管輪流導(dǎo)通來產(chǎn)生100kHz的高頻脈沖波，然后通過高頻變壓器進行降壓，輸出低電壓的交流電，高頻變壓器各個繞組線圈的匝數(shù)比例則決定了輸出電壓的多少。關(guān)于高頻變壓器是否可以安裝于辦公樓層一樓的問題，我們作出以下探討：</span></p>
<p> </p>
<p style="text-align: center"><span style="font-size: 14px"><img alt="高頻變壓器展?? width="334" height="262" src="/UploadFiles/FCK/高頻變壓??png" /></span></p>
<p><span style="font-size: 14px"> 1、為了避免傳導(dǎo)干擾的影響，可能的話，最好高頻變壓器放置于離辦公區(qū)一定距離的地方??/span></p>
<p> </p>
<p><span style="font-size: 14px"> 2、屏蔽是防止電磁干擾，增加高頻電源變壓器電磁兼容性的好辦法。但是為了阻止高頻電源變壓器的電磁干擾傳播，在設(shè)計磁芯結(jié)構(gòu)和設(shè)計繞組結(jié)構(gòu)也應(yīng)當(dāng)采取相應(yīng)的措施，只靠加外屏蔽帶并不一定是最佳方案，因為它只能阻止輻射干擾，不能阻止傳導(dǎo)干擾??/span></p>
<p> </p>
<p><span style="font-size: 14px"> 3、高頻變壓器使用條件包括兩方面內(nèi)容：可靠性和電磁兼容性。以前只注意可靠性，現(xiàn)在由于環(huán)境保護意識增強，必須注意電磁兼容性。電磁兼容性是指高頻電源變壓器既不產(chǎn)生對外界的電磁干擾，又能承受外界的電磁干擾。電磁干擾包括可聞的音頻噪聲和不可聞的高頻噪聲。高頻電源變壓器產(chǎn)生電磁干擾的主要原因之一是磁芯的磁致伸縮。磁致伸縮大的軟磁材料，產(chǎn)生的電磁干擾大.</span></p>
<p> </p>
<p><span style="font-size: 14px"> 掌握<a href="http://m.linhang.com.cn ">高頻變壓??/a>性能知識，正確選擇安裝高頻變壓器位置，有利于高頻變壓器的更好使用，使其發(fā)揮最大的優(yōu)勢??/span></p>
