我仿做了一台双变电源,用12只3DD207做,带动100W灯泡,亮度只有40W亮,关了一次灯泡,发现有拉弧现象,随即管子几乎全部报销.请高手指导.500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/83/3638661259594489.gif');}" onmousewheel="return imgzoom(this);">

1接错线,功率不出,管发热2主副变压器,T数不配
我是按照图做的,T数不会错,如果搭线错就不会起振了,如果改为前驱动,亮度则正常.

我做的是这个图,很容易出功率,就是管子质量不好的话很容易坏,你可以看看 发个好用的自激机 这个贴
