摘要:
三相三线有源滤波器( APF) 由于没有中性线,一般不考虑零序分量,通常采用二维空间矢量调制法( 2D-SVPWM) ,然而造成中性点电压偏移,使开关管电压应力加大。提出用三维空间矢量调制法( 3D-SVPWM) 对三相三线三电平有源滤波器进行调制,控制零序分量保证中点电压稳
定,间接控制直流侧电容电压的平衡。通过对3D-SVPWM 法开关时间进行归纳,发现开关时间只需根据参考矢量所在的相位划分成12 个扇区进行计算。因此可以去除子扇区的划分,简化了3DSVPWM的运算时间,同时消除子扇区划分误差。仿真与实验证明,采用所提出的优化3D-SVPWM法不但补偿谐波效果好,直流侧电容电压也较平衡。
Abstract:
Two-dimensional space vector modulation ( 2D-SVPWM) is applied in 3-phase 3-wire active power filter ( APF) ,which ignores zero sequence component,because it doesn’t have neutral line. The neutral-point voltage offset is caused and the voltage stress of switches increase. Three-dimensional space vector modulation ( 3D-SVPWM) was applied in 3-phase 3-wire three level APF. The neutral-point voltage was ensured and DC-link capacitor voltages was balanced through controlled zero sequence component.
After concluding the switches’duty time of 3D-SVPWM, it is found that the switches’ duty times are only related to the phase of reference vector and divided into 12 sections for calculating. Thus sub sections division was cut down,which shortens calculation and sub sections division error was eliminated.Finally,simulation and experimental results validate the correctness and feasibility of proposed algorithm.
