用一块9*7CM万能板制作SG3525+一对IRF3205,初级5+5,次级160.试机接100W灯200V不够. 空载时把频率调低一点8A电流,高时1A电流.5到7脚电阻为100欧,5脚对地电容为222,6脚为100K可调.请各位师傅指点下!先谢了..........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/77/3185481241532814.gif');}" onmousewheel="return imgzoom(this);">

首先谢楼上各位高手的指点先喔!从表面看SG3525应该是正品,5元一只.磁隙磨平,没虚焊,那我试下改变CT容量吧.我估计应该与万能板没关...
看我的,磁芯是EC40,3525+3205两队.前级空载130MA.加后级150.带风扇一共啊200MA.变压器是0.7*8*4匝俩组.次级0.5*2 大概100匝
