In this article,the authors analyze the aiguille voltage of the whole-bridge DC source converter circuit according to the mathematics model when the MOSFET transistor is shut and the instant voltage equations are obtained.
對(duì)直流電源變換器的常用電路型式進(jìn)行了具體工作過(guò)程分析 ;根據(jù)所建立的數(shù)學(xué)模型 ,分析MOS管關(guān)斷瞬間的尖峰電壓 ,得出其瞬間電壓方程 ,并應(yīng)用PSPICE軟件的仿真結(jié)果對(duì)其進(jìn)行驗(yàn)
For this reason,this paper base actual data of the essence characteristic, to discuss calculate formula VaR means in the the aiguille and fat tail branch, and make use of the calculate formula to carry out demonstration analysis for the stock market.
為此 ,本文從實(shí)際數(shù)據(jù)的基本特征出發(fā) ,討論了 Va R方法在尖峰、胖尾分布中的計(jì)算公式 ,并使用該計(jì)算公式對(duì)我國(guó)證券市場(chǎng)的實(shí)際數(shù)據(jù)進(jìn)行了實(shí)證分析 。
