摘要
本文中作者研究了三电平逆变器的调制策略,求证了三电平电力电子混合式变压器(PEHT)控制系统的中点电位自平衡性,并在Matlab/simulink仿真平台搭建了三电平PEHT模型,对控制过程进行了仿真分析。
The modulation strategy of the three-level inverter is studied by the authors in this paper,the self-balancing of the midpoint potential of the three-level power electronic hybrid transformer(PEHT)control system is proved.And a three-level PEHT model is built on the Matlab/simulink simulation platform,the control process is simulated and analyzed.
