本文提出了一种定量估计逆变器系统传导辐射的方法，为EMI滤波器的优化设计提供了依据。提出的方法的基本概念是使用电路模拟器，对逆变器系统的组件进行详细建模，即无源器件、开关器件和测量仪器。该方法以CISPR 22中规定的形式提供了逆变器的传导发射，也就是说，仿真结果可以直接与实验进行比较。结果表明，在150 kHz~5 MHz范围内，仿真结果与实验结果吻合较好，误差为±6dB。该方法的最大好处是可以实现传导发射的模式分离，包括差模和共模。本文对此进行了讨论和分析，充分利用了这一优势，大大提高了EMI滤波器的设计效率。
This paper proposes a method for quantitative estimation of conducted emission from an inverter system, which helps the optimal design of EMI filters. The basic concept of the proposed method is the usage of a circuit simulator with detailed modeling of the components of the inverter system, i.e. passive devices, switching devices, and measurement instruments. The proposed method provides the conducted emission of the inverter in the form prescribed in CISPR 22, that is, the simulation results can be compared to the experiments directly. It is revealed that the simulation result agrees very well with the experiment with the error of ±6dB ranging from 150kHz to 5MHz. A great benefit from the proposed method is that the mode separation, differential and common, of the conducted emission becomes possible. Discussions and analyses are set forth in this paper with making full use of this benefit, which greatly makes the design of the EMI filter efficient.
