Proposes a control method without circulation,which aims at the shortcomings of existent widespread bivariate AC-AC converter.
针对目前被广泛应用的交-交变频器存在的缺点,提出了一种自然无环流双变量交-交变频器的控制方法,并把变频器的频率输出范围扩大到非整数分频,使输出频率的上限达到输入频率的1/2以上,调速级差达到很小,实现了无环流、无死区、无检测、无反馈、全开环、调速级差小调速范围宽的交-交变频器,其调速系统成本更低,可以实现能量的双向流动,容易实现四象限运行。
For studying the internal relativities on volatility between SH and SZ warrants and underlying stocks, a bivariate EGARCH model is developed that includes cointegrating residuals as an explanatory variable for the co
在实证研究中,作者进行了两项创新,其一是开创性的论述了双变量EGARCH模型在研究权证和基础市场关系中的合理性:本文首先把我国沪深A股市场中的认股权证及其标的股票对数价格之间的协整残差项作为解释变量分别引入条件均值方程和条件对数方差方程,并在正股(权证)的条件对数方差方程中加入了权证(正股)的滞后一阶条件对数方差项,建立了双变量的EGARCH模型。
