现在还没有回复呢,说说你的想法
1525的11脚输出脉冲一直在抖动,但是电路输出电压稳定.带大负载时变压器有杂音出现,轻载(很轻的负载)能力也不行.

AC160-260V输入,DC115V输出.1525的11脚输出频率为50KHz.变压器原边48匝 次边43匝,都是2*0.80并绕.
下面是反馈参数及输出参数.请各位帮助分析一下.谢谢大家.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/55/147491184115261.bmp');}" onmousewheel="return imgzoom(this);">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/55/147491184115346.bmp');}" onmousewheel="return imgzoom(this);">
