Abstract:

在满足相同的高频滤波效果的情况下,LCL滤波器所需的总电感值比L滤波器小,因此更适于在大功率、开关频率较低的电流源控制型并网设备上应用。然而针对该类型滤波器的参数设计不仅关系到开关频率处纹波抑制效果,同时也会影响并网电流控制器的性能。本文首先建立LCL滤波器在并网模式下的谐波模型,其次研究滤波器各参数变化与纹波抑制和谐振频率之间的变化关系,在此基础上提出在尽量节约总的电感磁心材料的前提下,设计出滤波效果最优的LCL滤波器的参数值,同时还需要保证LCL滤波器的谐振频率不能太小,以免成为制约电流控制器设计时的因素。最后通过三相并网逆变器的实验装置给出LCL滤波器设计方案的实验效果。
