摘要

本文的目的是利用不连续三维空间矢量调制(D3DSVM)进一步提高三相四脚逆变器的功率传输效率。通过线性变换建立三维坐标，划分空间矢量截面。对各切换矢量进行了研究，并对各时间分配的计算方法进行了分析和总结。根据不同的计算规则，给出了D3DSVM的四种具体实现算法。比较了四种D3DSVM方法下逆变器输出电压的谐波畸变、系统的输电效率和开关损耗。仿真和实验结果验证了该方法的可行性。

Research on a discontinuous three-dimensional space vector modulation strategy for the three-phase four-leg inverter

The objective of this paper is to further improve the power transmission efficiency of a three-phase four-leg inverter by means of discontinuous three-dimensional space vector modulation (D3DSVM). Three-dimensional coordinate is established by linear transformation, and space vector sections are divided. Each switching vector is studied, and the calculation method of each time allocation is analyzed and summarized. Based on the different calculation rules, four specific implementation algorithms for D3DSVM are obtained. Harmonic distortion of the inverter output voltage and system power transmission efficiency as well as switching losses under four D3DSVM methods are compared. The feasibility of the proposed method is verified through simulation and experimental results.
