首先祝贺一下.小电流情况下使用运放+MOSFET的方法,问题不大.但是如果电流比较大,像你以前做的10A的驱动,效率问题就出来了.MOSFET会严重发热,不知道你的10A的驱动做的怎么样了.我的40A的808LD驱动已经完成了,效果相当不错.各种指标都已经达到要求,有过压,过流保护,有使能连锁接口.效率在77%以上.下一步60A带数控监视,计时功能.[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/82/2354671254699085.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/82/2354671254699253.jpg');}"onmousewheel="returnimgzoom(this);">
