| 摘 要： | 通过对三相四开关并联型有源电力滤波器(TFSAPF)的电路进行分析,考虑TFSAPF只有4个模值不全相等的有效电压空间矢量,不存在零矢量,并考虑到电压空间矢量U1和U3大小相等、方向相反,因此本文将U1和U3同时作用相同的时间以获得等效的零矢量,提出了一种适用于TFSAPF的SVPWM调制算法.相关的仿真与实验结果均证...

| Abstract: | According to the circuit analysis diagram under different switching modes,considering only four active voltage space vectors without zero voltage space in the TFSAPF,this paper makes duration time of the voltage space vectors U1 and U3 equal to form the zero voltage space vector when amplitudes of U1 and U3 are same while their directions are opposite.A pulse width modulation method based on voltage space vectors is proposed in this paper for three-phase four-switch shunt active power filter(TFSAPF).Some si... |
