| 摘 要： | 此处研究了基于谐波频谱的LCL滤波器设计。针对LCL滤波三相并网逆变器,给出采用空间矢量脉宽调制(SVPWM)方法控制的逆变桥桥臂电压输出谐波。依据EMI滤波器设计的方法,研究谐波频谱与谐振频率之间的关系,得出LCL滤波器的谐振频率。在此基础上,设计出满足并网要求且总电感量最小的LCL滤波器。最后通过三相并网逆变器的实验装置给出了LCL滤波器设计方案的实验效果。

| Abstract: | The design of LCL filter based on harmonic spectrum is presented.The output harmonic of inverter bridge leg of three-phase inverter with LCL filter is controled by using space vector pulse width modulation(SVPWM).According to the design process of EMI filter,the relationship between harmonic spectrum and the resonant frequency is studied and the resonant frequency is obtained.In order to satisfy the standard and achieve the LCL filter with minimum inductance,a reasonable design method is brought out based on above analysis.Finally,the design method is verified by the experimental results. |
