我最近在开发48VDC输入220VAC(正弦波)输出,功率为2000W,电池升压成正负380VDC,请问要控制正负380V直流电压稳定在正负2%,升压控制IC用3525,需将升压电路与输出用光藕隔离,有什么好的方案请各位大哥们不要吝啬噢!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/20/1093959384.bmp');}" onmousewheel="return imgzoom(this);">
