The Electromagnetic susceptibility (EMS) of cathode ray tube (CRT) display for computer was investigated preliminarily using the test method of bulk current injection (BCI). During the test, CW signals as electromagnetic interference (EMI) signals with different amplitude at a certain frequency were injected into the RGB, horizontal synchronization (HS) and vertical synchronization (VS) signal line...
In this paper, the effects of high power and frequency radiated RF interference on a high speed low voltage differential signaling (LVDS) system are investigated for electromagnetic susceptibility (EMS) of LVDS. The improvement method of EMS on LVDS is proposed by using common mode self-rejection (CMSR) flexible printed cable (FPC). External electromagnetic noise source such as an antenna in mobile...
According to describing EMS characteristics of subsystems and components in a complicated Electronic system, this paper put forward a behavioral simulation method to establish EMS characteristics behavioral model of the whole system, then the EMS problems can be analysed and predicted easily. This method discriminates the characteristics of radiation sensitivity/ radiation path from conduction sensitivity/...
To realize systematic analysis for electromagnetic susceptibility (EMS), forecast for electromagnetic compatibility (EMC), a modeling method on electromagnetic interference coupling path of digital relay in power system was presented. The simulated model of electromagnetic interference coupling path can be gotten by this method through the system identifying according to the experiment data. A mathematical...
This paper presents the field uniformity characteristics of a triangular reverberation chamber which can be substituted for an open area test site or an anechoic chamber to measure EMI and EMS. Three kinds of equilateral triangular reverberation chambers with the same volume are designed, and field distributions are simulated. Field deviations of each structure using XFDTD 5, 3 of FDTD (finite difference...
In EMS (electromagnetic susceptibility) simulation of electronic devices, the mathematical modeling can be adopted to conduct systematic analysis of EMS and optimization of the filter design. This paper has presented one modeling method for the EMS simulation analysis of electronic devices, based on the system identification supported by experimental data. A mathematical modeling of the power module...
