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.
对直流电源变换器的常用电路型式进行了具体工作过程分析 ;根据所建立的数学模型 ,分析MOS管关断瞬间的尖峰电压 ,得出其瞬间电压方程 ,并应用PSPICE软件的仿真结果对其进行验
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.
为此 ,本文从实际数据的基本特征出发 ,讨论了 Va R方法在尖峰、胖尾分布中的计算公式 ,并使用该计算公式对我国证券市场的实际数据进行了实证分析 。
