LCL滤波器串联阻尼参数优化新方法
|
摘要
基于L型与LCL型输出滤波器的特点,指出了LCL振尖峰的问题,指出应用传统无源阻尼法可以较好的消除谐振尖峰,但传统的无源阻尼参数设计方法可能会引入较大的阻尼损耗,本文综合考虑了阻尼损耗以及衰减系数对于阻尼电阻的约束条件,优化了串联阻尼计算方法,通过仿真证明该方法可以较好的消除谐振尖峰并减小阻尼损耗。
Based on the characteristics of L and LCL output filter,the problem of LCL filter will introduce resonantpeak is pointed out. The traditional passive damping method can eliminate the resonant peak. However,the traditional passive damping parameter design method may cause a great damping loss. In this paper,the series damping calculation method is optimized by considering the constraints of the damping loss and attenuation coefficient on the damping resistance. The simulation results show that this method can eliminate the resonant peak and reduce the damping loss.
