摘要

针对传统电流源变流器的调制方法无法实现三相四桥臂电流源变流器在不平衡负载下的三相电压平衡控制，且会有较高的共模电压的问题，提出了一种三相四桥臂电流源变流器的三维空间矢量脉宽调制（3D-SVPWM）方法，并将其应用于三相四线制独立供电系统。首先

定义了三维电流空间矢量，分析了不同电流空间矢量对应的共模电压。其次

提出了判断参考矢量所在四面体的方法。然后

通过优化空间矢量顺序，提出一种低开关动作次数下有效减小共模电压的空间矢量顺序。最后

实验表明所提3D-SVPWM方法能够实现三相四桥臂电流源变流器在不平衡负载下的三相电压平衡控制，且能有效降低共模电压。

Abstract

The conventional modulation method of current-source converter cannot realize the three-phase voltage balance control of the three-phase four-leg current-source converter with unbalanced load

and has a high common-mode voltage. To solve the above problems

this paper proposes a three-dimensional space vector pulse width modulation (3D-SVPWM) method for the three-phase four-leg current-source converter

and applies it to a three-phase four-wire independent power supply system. Firstly

the three-dimensional current space vectors are defined

and the common-mode voltages corresponding to different current space vectors are analyzed. Secondly

this paper proposes a method for judging the tetrahedron where the reference vector is located. Thirdly

by optimizing the space vector sequence

this paper proposes a space vector sequence which can effectively reduce the common-mode voltage at low switching times. Finally

the experiments show that the proposed 3D-SVPWM method can achieve three-phase voltage balance control on three-phase four-leg current-source converter with unbalanced load

and effectively reduce the common-mode voltage.
