摘要

研究了有源电磁干扰滤波器中变压器隔离对浪涌抗扰度的影响。通过实验分析了浪涌对有源电路部件的影响。分别测量了电容直接耦合和变压器隔离耦合两种情况下，电流感应电流补偿(CSCC) AEF中浪涌暂态电压传递到有源电路部分的最大峰值电压和脉冲持续时间。通过大量的4kV浪涌试验和VNA测试，验证了所设计的变压器隔离CSCC AEF的浪涌抗扰性。

Improvement of Surge Immunity by Using Transformer-isolation in an Active EMI Filter

Improvement of surge immunity due to transformer-isolation in an active EMI filter (AEF) is investigated. The surge influence on active circuit parts is analyzed by experiments. Maximum peak voltage and pulse duration of the surge transient voltages transferred to active circuit parts of a current-sense current-compensation (CSCC) AEF are measured in the cases with direct capacitive coupling and transformer-isolated coupling, respectively. The surge immunity of the designed transformer-isolated CSCC AEF is validated under numerous 4kV surge tests and VNA measurement.
