柵極中和法
英文
grid neutrodyne method-
In the experiment we try to find out some ways to improve the performance of the positive pole through the study of positive active material and anode grid
在實驗中我們力圖想通過添加劑的研究和板柵的研究找出提高正極性能的辦法。Because of the limitation of experimental conditions we failed to form foam lead grid in the experiment. copper draw net is used as anode grid and it can improve to some extent the utilization of pam. due to human errors in the experiment we have not used the same discharge current density
在實驗中我們試圖通過鑄造法、電鍍法和還原法等一系列的實驗辦法製作泡沫鉛板柵,由於實驗條件的限制,沒能夠成功制得泡沫鉛,而在使用銅拉網作為正極板柵的時候,能夠使電池的正極活性物質利用率有提高,但由於實驗時候的失誤,沒能夠使用相同的放電電流密度進行放電,我們無法利用實驗數據比較出具體能提高的數字。The solution of the interior problem has been obtained by the fem method. ensuring the continuity of the tangential electric field across the aperture plane, the electromagnetic e and h has been gained
分別採用有限元法和矩量法分析封閉腔體和半無限空間的電磁場,在孔徑面上進行邊界條件匹配,從而得出極化雙工柵中的電磁場特性。According to the following design theory : the dsp calculates in real time and produces three phases spwm waves to control the on or off of the 6 igbts in ipm respectively. ipm then inverts the commutated single phase direct current ( insulated gate bipolar transistor ) into three phases alternating current. when modulated signals of spwm are changed, the on - off time of switches also changes, so as to the voltage and frequency of output signals
本文提出了一種基於dsp (數字信號處理器tms320f240 )的通用的三相間接變頻電源系統,利用分段同步調製法和混合查表法,實時計算不同頻率下的采樣周期、電壓幅值、輸出脈寬,產生雙極性spwm波形,經驅動放大後用于ipm ( intelligentpowermodule )中的絕緣柵雙極型晶體管柵級驅動,以控制電源的輸出電壓和頻率,實現變頻電源的智能數字控制。The full noise and linearity analysis of the low noise amplifier ( lna ) constructed by cascode structure with source degeneration and the optimization methods of the two mosfets in this structure according to the noise and linearity performance
