摘要

为了实现对IGBT PWM逆变器中电磁干扰噪声的预测，本文提出了一种新的实用的电磁干扰噪声源建模方法。采用频率域等效的特文宁源，包括电压源和源阻抗，对主要的电磁干扰噪声源——IGBT开关进行建模。研究了差模和共模噪声源的建模方法。该方法在一个简单的可控试验台上得到了实验验证。对测量重复性和数据处理等重要问题也进行了研究和讨论。

Experimental evaluation of IGBTs for characterizing and modeling conducted EMI emission in PWM inverters

As a step to achieve the objective of predicting electromagnetic interference (EMI) noise in IGBT PWM inverters, this paper proposes a new and practical EMI noise source modeling method. An equivalent Thevenin source in the frequency-domain, including the voltage source and source impedance, is employed to model the main EMI noise emission source - the IGBT switching. The modeling approach for both the differential mode (DM) and common mode (CM) noise source is studied. The methodology is verified experimentally using a simple, controlled testbed. The important issues on measurement repeatability and data processing are also investigated and discussed.
