摘　　要：变频器由于其IGBT高频运行方式,不可避免地产生了大量的电磁噪声。基于线性阻抗稳定网络(LISN)的测量方法多适用于中小功率变频器,对于大功率变频设备如果采用该方法,测试设备将非常昂贵。从传导发射测试的实质出发,设计了一种基于电源滤波器配合高压探头的大功率变频器传导骚扰测试的方法,通过对大功率开关磁阻电机的变频器进行传导骚扰测试,证明了该方法的有效性。Due to IGBT inverter operation in the high frequency mode, inevitably, produced a lot of electromagnetic noise. The measurement method for small and medium-sized power converter based on LISN is applicable, but for high-power inverter equipment, the test equipment is very expensive. From the essence of conducted emission test, designed a kind of conduction harassment test method for high- power inverter based on the power filter with the high pressure probe, meanwhile, proved that this method is valid through conducted harassment test for the high-power switched reluctance motor converter.
