1:反馈应该如下:[图片]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){returntrue;}else{window.open('http://u.dianyuan.com/bbs/u/26/1108922392.jpg');}"onmousewheel="returnimgzoom(this);">
2:增加补偿电容C?
3:输出线圈反了,同名端如下图
4:匝数有误,按你现在的规格VCC=19.16V,Vout=45.7V
4.1:Nout改为11Ts,则Vout=35.8V,但是此时反射电压150V,加上漏感可能超过210V,主开关管耐压没有余量.
4.2:Nb为9Ts,Nout为16Ts,则Vout=34.6V,此时反射电压为100V.
