摘要
传统有源电力滤波器输出波形中纹波含量较高,严重影响有源电力滤波器内电解电容的使用寿命。采用双重化PWM技术,在传统有源电力滤波器拓扑结构基础上进行改进,通过仿真图形的比较分析,验证了改进型有源电力滤波装置能够有效减少输出波形中的纹波含量。
The ripple content in output waveform of the traditional active power filter is high,which seriously influences the service life of the electrolytic capacitor in the active power filter. Having dual PWM technology adopted and improved on basis of the traditional active power filter topology was implemented. Comparative analysis of graphic simulation shows that,this improved active power filter can effectively reduce the ripple content in the output waveform.
