| Objective To study the mathematical model of electromagnetic interference transmitter in electromagnetic compatibility analysis. Methods The composition and emission principle of electromagnetic interference transmitter were analyzed. The power models and frequency models of fundamental wave, harmonic wave, anharmonic wave and inter-modulation wave eradiate from transmitter were studied, and the getparms method of correlative parameters was investigated. Results The relatively complete models, the methods of piecewise linear approximation of modulation envelope and the measure methods of correlative parameters were presented. Conclusion The result of transmitter modeling could provide reference for electromagnetic compatibility predictive analysis and simulation. |
