In order to solve the problems of power line interference conduction emission test, this paper models and analyzes the power line interference using frequency-domain transmission line theory. Based on TLM and the model, this paper presents a fast computation method for conduction current and voltage distribution caused by common-mode and different-mode signal in power line.
This paper stated a novel method of protecting power amplifier in electromagnetic susceptibility (EMS) test. According to little changing of SWR amplitude with fixed impedance, the possible large power output could be predicted based on the current low power, achieving the aim of equipment protection. It is proved in actual test example that that novel method could be operated expediently and put...
In the electromagnetic compatibility test, some need to carry out under strong external electromagnetic environment, people can not be a close observation of the test items, in which an ordinary video monitor will also be a serious interference. This paper present a new set of EMC solutions through solving the video monitor interference within the band of 20 MHz–200 MHz in the strong external electromagnetic...
