我用运放搭了一个反馈控制回路,如下图所示,但自己做的6.1mH电感总"吱吱"响,示波器测得输出存在较大干扰,开关管两端的控制信号也极不稳定,甚至DC输出源也存在些许干扰,拜求各位高人帮忙分析一下吧,谢谢~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/57/1613551188631835.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">
