看到這樣一句話:
it dose not cause ground bounce problem
里面的ground bounce problem是什么意思?
哪位知道,請說一下,謝謝!
怎么翻譯?

多謝!還有下面兩句不太懂,麻煩幫我看看吧!
1.The turn-off transistor shunts out the gate drive loop inductance, the potential current sense resistor, and the output impedance of the driver. 里面的shunts out 和 potential current sense resistor
2.the gate of the main MOSFET is floating before the outputs of the driver IC becomes intelligent during power up.里面的becomes intelligent during power up
謝謝!

難啊．我也看不懂．把電路傳上來,或許能猜出來．shunt out 可能指并聯．potential current sense resistor 可能指磁化電流感測電阻．第二句大概指,上電期間,在驅動IC的輸出變得智能化之前,主MOS的柵極是浮置的．這個intelligent 估計指能夠自動控制吧．我只能瞎猜了．

第一個圖對應第一句話,第二個對應第二句.請你再看一下.謝謝!

不好意思發錯了,第二個圖是下面這個:

第一句的意思應是這樣的:(當Qoff導通時),它就把驅動回路電感,驅動器的輸出阻抗,及potential current resistor給旁路掉了,(使得關斷速度邊快了)．potential current resistor你沒畫出來,估計是磁化電流傳感電阻．第二句就是我說的哪個意思,及上電期間,芯片還未開始工作,沒有輸出時,MOS柵極是浮置的．
