The filter is composed of an active filter (AF) and a passive filter (PF).

滤波器是由有源滤波器(AF)和无源滤波器(PF)串联组成。

This method is also suited to design approximation function of passive filter.

这种方法同样适用无滤波器的近似函数设计。

So EMI passive filter of motor system is composed by mains filter and output side filter.

电机系统emi无源滤波器由电源滤波器和输出侧滤波器组成。

These passive components can be used as basic building elements to make a passive filter.

这些无源元件是构成无源滤波器的基本元件。

Governing harmonic with Active Power Filter has better compensation performances than with Passive Filter.

采用有源电力滤波器治理谐波比无源滤波器有更优越的补偿性。
