摘要
基于传统滤除谐振的方法滤除谐波不够彻底且响应速度比较慢的问题,提出了一种优化滤除谐振的方法,针对性地设计了一种优化后的阻尼器,可快速滤除逆变系统内产生的高次谐波。该阻尼器是基于带通滤波器组成,通过在Simulink上进行的模拟实验,分析滤波前后的波形对比,验证了优化后的阻尼器可以有效降低逆变器系统中的谐振及50次以上的高次谐波。
Based on the problem that the traditional filtering resonance method doesn’t eliminate harmonics completely and responses slowly,this paper proposed a kind of optimized filtering resonance method.The optimized damper was designed to quickly filter out the higher harmonics generated in the inverter system.This damper was based on the band-pass filter.The simulation experiments in Simulink could be used to compare the waveform before filtering with the one after filtering.It is verified that the optimized damper could effectively reduce the resonance which is higher than 50 times in the inverter system.
