【摘要】 在分析双级矩阵变换器控制原理的基础上,提出了一种过调制控制策略,该策略分为两步:先改进双级矩阵变换器整流器的控制策略,使其整流侧得到尽可能大的直流整流电压,然后研究双级矩阵变换器逆变器的过调制控制策略,增大逆变器输出电压,从而实现电压传输比的提高.文中在过调制控制原理的基础上,基于DSP和CPLD建立了一套双级矩阵变换器实验装置,实验证明:双级矩阵变换器过调制策略能有效提高电压传输比,从而验证了该过调制策略的正确性.更多还原

【Abstract】 This paper put forward an over modulation strategy on the analysis of two-stage matrix converter control theory.The strategy is divided into two steps.First,the strategy gets the maximum DC voltage through the control of the rectifier,second,the converter is over modulated,which effectively improve the voltage transfer ratio.A set of experiment device of two-stage matrix converter is built with DSP and CPLD on the basis of over modulation control theory.Experiment result testify that the over modulation strategy can effectively improve voltage transfer ratio,which verify the validity of the strategy.更多还原
