摘要

本文介绍了单相PWM逆变器输出LC滤波器的分析与设计方法。首先推导了LC滤波器电感电流和电容电压总谐波的解析表达式。由于不能仅根据电容器电压的总谐波来指定LC滤波器参数的唯一值，因此使用基于LC滤波器的最小无功功率的附加准则来指定这些参数。实验结果验证了推导出的表达式。

An LC filter design method for single-phase PWM inverters

In this paper, an analysis and design method of the output LC filter of single-phase PWM inverters is presented. At first, the analytical expressions for the total harmonics of the inductor current and capacitor voltage of the LC filter are derived. As the unique values of the parameters of the LC filter cannot be specified based on the total harmonic of the capacitor voltage alone an additional criterion based on the minimum reactive power of the LC filter is used to specify these parameters. Experimental results are included to verify the derived expressions.<>
