张老,我试了下,将初级加到17T,我用试波器看,空载时打开的脉宽要比少些时候要打开大些,如此看来,初级加大后,变压器要到达同样的储能,时间就要长一些,到带载时一定达不到需求的功率.还有就是我看了一款日本的升压电源,DC9.6V输入,DC450V输出,采用EI28(PC40)磁芯,初级用7T,输出用240T,工作波形如下:[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/72/711231229401345.jpg');}"onmousewheel="returnimgzoom(this);">[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/72/711231229401357.jpg');}"onmousewheel="returnimgzoom(this);">以下是我现在的波形:[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/72/711231229401637.jpg');}"onmousewheel="returnimgzoom(this);">[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/72/711231229401688.jpg');}"onmousewheel="returnimgzoom(this);">[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/72/711231229401713.jpg');}"onmousewheel="returnimgzoom(this);">
