我上傳一個(gè)比較簡單的參數(shù)計(jì)算公式和原理圖1105067088.zip

這是計(jì)算葉面

這是原本的模型,我看不出哪里錯(cuò)?

在模型里面,有個(gè)地和Vin接在一起了.
在仿真的時(shí)候波形不會正常的,自己試試吧.
saber公司總部給了一個(gè)正確的模型給我門公司.
:)

能把正確的模型發(fā)上來嗎?謝謝!

謝了,但看不出有啥區(qū)別啊!

是不對,你的是正確的嗎?

這個(gè)是正確的嗎?

這個(gè)是saber2007里面自帶的那個(gè),我看了一下,一模一樣的.

這個(gè)只是在原理圖中查看元件屬性時(shí)看到的,用寫字板打開它的原文時(shí),還有好多東西看不明白.全是數(shù)字.

都是加密文件,能看明白才怪呢
