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.

對直流電源變換器的常用電路型式進行了具體工作過程分析 ;根據所建立的數學模型 ,分析MOS管關斷瞬間的尖峰電壓 ,得出其瞬間電壓方程 ,并應用PSPICE軟件的仿真結果對其進行驗

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 ,本文從實際數據的基本特征出發 ,討論了 Va R方法在尖峰、胖尾分布中的計算公式 ,并使用該計算公式對我國證券市場的實際數據進行了實證分析 。
