The behavioral simulation of EMI system by DNA method at the system level

A behavioral-level simulation technique that can be used together with the nonlinear discrete technique for a system-level electromagnetic compatibility and electromagnetic interference (EMC/EMI) analysis. According to nonlinear interference sources and the transmission matrix, a complicated system was separated into many DNA models, thus carried out the complicated system to imitate true and analytical. The technique presented allows one to simulate a system in the time domain mode as well as in the frequency domain mode by taking into account the nonlinearity transfer characteristics. The technique was validated by making comparisons with measurements and simulation data.
