| Abstract |
This paper derives the closed-loop impedance model for the typical three-phase active rectifier andinvestigates the dominant factors influencing the converter impedance below 150 kHz frequency range from the basic performance (e.g., steady-state and dynamic performance) and EMI perspectives. Therefore, the complete modeling process of the closed-loop impedance is described,including the control analysis and impedance modeling. The discussion of improving basic performances and EMI performance for the power converter is proposed. Moreover, an advanced impedance measurement technique is introduced. Finally, the validation of the derived closed loop impedance model and the dominant influence analysis for the three-phase rectifier are carried out in MATLAB and PLECS. |
