| 摘 要： | 针对三相四桥臂逆变器现有电流调节方案存在的某些问题，提出了一种改进的基于三雏空间电压矢量的电流调节方案．整个方案仅需三个最高开关频率受限的三电平比较器和相应的电压矢量选择表，实现简单，参数调整方便。文中对其原理进行了理论分析，给出了三相四桥臂逆变器带不平衡负载和作为三相四线有源电力滤波器应用时的仿真结果，验证了其正确性和可行性。

| Abstract: | Aiming at the limitation of some presented current regulation schemes for three-phase four-leg inverter, a modified current regulation scheme based on three-dimensional space voltage vectors is presented. Whole scheme only needs 3 three-level comparators whose maximum switching frequency is limited and a corresponding voltage vectors selection table, thus the realization is very simple and the adjustment of parameters is very convenient. Theoretical analysis about its principle is provided; Simulation results under unbalanced loads and under the condition when three-phase four-leg inverter is used as a three-phase four-wire parallel active power filter are presented too, and the validity is verified. |
