Abstract :
This paper presents a study of conducted EMI emission in PWM inverter complying with the EMC standard in 15 kHz to 50 MHz range. All major circuit components including switching IGBT, passive components and interconnects are modeled in high frequency domain. Common mode and differential mode switching noise together with EMI´s filter design and topology are the key aspects that have been considered. In addition, the paper reports the conducted EMI measurements results for PWM inverter that have turned to be decisive in the reduction of the conducted EMI.
