重新饶了两种变压器:第一种是Np=122Ts,Ns=8Ts,Na=24Ts,Lp=2.5mH 通电测试空载85V输入Vcc=8.518V,265V输入Vcc=4.820V 带0.2A负载,85V输入时Vcc=8.898V,开关波形如下[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/56/89481188028028.jpg');}"onmousewheel="returnimgzoom(this);"> 265V输入时,Vcc=10.430V,开关波形如下:[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/56/89481188028067.jpg');}"onmousewheel="returnimgzoom(this);">第二种变压器,Np=122Ts,Ns=7Ts,Na=21Ts,Lp=2.5mH 通电测试空载85V输入Vcc=6.401V,265V输入Vcc=4.821V 带0.2A负载,85V输入时Vcc=9.055V,开关波形如下[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/56/89481188028153.jpg');}"onmousewheel="returnimgzoom(this);"> 265V输入时Vcc=10.252V,开关波形如下:[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/56/89481188028252.jpg');}"onmousewheel="returnimgzoom(this);">请问一下,结合波形和Vcc电压,哪个变压器要理想一点?
