由于产品需要扩展使用范围交、直流两用,需做一个交、直流输入逆变模块,正弦波逆变,带感性负载,我用直接整流后用MOSFET全桥逆变,驱动采用国产U296正弦波调制驱动,左半桥采用20KHZ调制,右半桥采用50HZ调制,经电容滤波后交流输出,请给予此方法一些指正了,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/31/1120199499.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">1120199752.sch
