一种电流源型三相逆变器模型

摘要

A 3-phase current-source inverter is mathematically modeled and analyzed in this paper.Firstly,the basic coordinate transformation is described;secondly,this paper derives a mathematical model of 3-phase current-source inverter in the d-q coordinate system and gives its block diagram;lastly,this paper analyzes the parameters related to the inverter,including power factor,harmonic state and output filter design.%对电流源型三相逆变器进行数学建模与分析。首先介绍了基本的坐标变换；其次以电流源型三相逆变器的原理为基础，在d-q坐标系下，推导出其数学模型，并画出了结构框图；最后分析了逆变器的相关参数，包括功率因数、谐波状态和输出滤波器设计。
