重新饒了兩種變壓器:
第一種是Np=122Ts,Ns=8Ts,Na=24Ts,Lp=2.5mH
通電測試空載85V輸入Vcc=8.518V,265V輸入Vcc=4.820V
帶0.2A負(fù)載,85V輸入時Vcc=8.898V,開關(guān)波形如下

500) {this.resized=true; this.width=500; this.alt='這是一張縮略圖,點擊可放大。\n按住CTRL,滾動鼠標(biāo)滾輪可自由縮放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/56/89481188028028.jpg');}" onmousewheel="return imgzoom(this);">
265V輸入時,Vcc=10.430V,開關(guān)波形如下:

500) {this.resized=true; this.width=500; this.alt='這是一張縮略圖,點擊可放大。\n按住CTRL,滾動鼠標(biāo)滾輪可自由縮放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/56/89481188028067.jpg');}" onmousewheel="return imgzoom(this);">
第二種變壓器,Np=122Ts,Ns=7Ts,Na=21Ts,Lp=2.5mH
通電測試空載85V輸入Vcc=6.401V,265V輸入Vcc=4.821V
帶0.2A負(fù)載,85V輸入時Vcc=9.055V,開關(guān)波形如下

500) {this.resized=true; this.width=500; this.alt='這是一張縮略圖,點擊可放大。\n按住CTRL,滾動鼠標(biāo)滾輪可自由縮放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/56/89481188028153.jpg');}" onmousewheel="return imgzoom(this);">
265V輸入時Vcc=10.252V,開關(guān)波形如下:

500) {this.resized=true; this.width=500; this.alt='這是一張縮略圖,點擊可放大。\n按住CTRL,滾動鼠標(biāo)滾輪可自由縮放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/56/89481188028252.jpg');}" onmousewheel="return imgzoom(this);">
請問一下,結(jié)合波形和Vcc電壓,哪個變壓器要理想一點?
