摘要
提出了一种适于测量离线式变换器传导电磁干扰特性的新方法 ,可以便捷地测出离线式变换器传导电磁干扰的等效干扰源和等效内阻抗特性 ,有效地指导电源EMI滤波器的设计。本文对测量原理、测量步骤进行了详细介绍 。
A novel method for measuring the conducted EMI feature of an off line converter is proposed. By this measurement, the equivalent conducted EMI sources and internal impedance can be easily educed so as to guide the design of EMI filter effectively. The measurement principle and procedure are described in detail and the method is verified by experiment of an off line AC/DC converter.
