大家好!在学习NCP1207做一个谐振电源,官方的应用电路看不出怎么构成谐振回路的,通常谐振回路有LC构成,在MOSFET管并一个电容,但这个官方电路没有,请教各位帮忙指出其谐振回路和谐振形成原理,小弟学习学习!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/81/3574521253368501.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">
