| 摘 要： | 为解决传统大功率开关电源系统中，整流侧产生大量谐波电流而使得系统的输入功率因素低，且谐波畸变率（Trio）高的问题，本文基于TMS3320FL2407系列DSP，采用空间矢量脉宽调制（SPWM）技术，设计出矩阵式开关电源系统．经仿真实验分析．矩阵式开关电源系统可以有效地改善输入侧电流波形质量，并使得系统的功率密度有所提高．

| Abstract: | In traditional large power switch mode power supply system,the rectifiers draw significant harmonic currents from the utility,resulting in poor input power factor with high total harmonic distortion(THD).To solve this problem,based on TMS3320FL2407 DSP,by means of space vector modulation technology,the paper designs a matrix converter switch mode power supply system.Analysis of simulating experiment shows that matrix converter switch mode power supply system can improve input current quality,and that power ... |
