Abstract

This article is dedicated to modeling of the emission device of industrial radio interference based on the clock generator, which in real devices is the most common cause of electromagnetic compatibility problems. The device under test consists of a clock generator and two inverters connected through long printed conductors. Simulation results are obtained in CST Microwave Studio, with the simulation conditions close to measuring the emitted interference according to the standards. The results obtained are compared with the actual experiment in an semi-anechoic chamber. It is shown that the simulation of the device and the subsequent correct measurement of the parameters of emitted fields make it possible to obtain a fairly accurate approximation to the measurement results carried out in a semi-anechoic chamber of a real device at a lower cost. Such a method will allow identifying electromagnetic compatibility problems in the device at the development stage.

基于时钟发生器的工业无线电干扰发射装置建模

基于时钟发生器的工业无线电干扰发射装置是实际设备中最常见的电磁兼容问题，本文对其进行了建模。测试中的设备由一个时钟发生器和两个通过长印刷导体连接的逆变器组成。在CST Microwave Studio中获得了仿真结果，仿真条件接近于按标准测量发射干扰。所得结果与半消声室的实际实验结果进行了比较。结果表明，对该装置进行仿真并对发射场参数进行正确测量，可以以较低的成本获得与实际装置半消声室测量结果相当精确的近似值。这种方法将允许在开发阶段识别设备中的电磁兼容性问题。
