摘要
相同的有源EMI滤波器在不同的源阻抗和负载阻抗条件下,滤波特性有很大差异。文中以电流检测电流补偿型有源EMI滤波器为例,分析了在负载分别为纯阻性、感性和容性条件下的滤波特性,并给出了有源EMI滤波器的适应条件。
The performance of an active EMI filter varies with source impedance and load impedance. The filter performance has been discussed, when the load were pure resistance, capacitive impedance and inductive impedance based on current detection current compensation active EMI filters. At last, the proper application conditions for this active EMI filter are concluded.
