Study on Conduction EMI Noise for EMC Filter Mounted on Switching Power Supply

In the power electronics field, the movement of the conduction EMI standard to be expanded to 150 kHz or less is being carried out at IEC. In the frequency range below 150 kHz, it is necessary to take measures against noise from the fundamental wave. In this report, we describe the situations that t...

Zusammenfassung:In the power electronics field, the movement of the conduction EMI standard to be expanded to 150 kHz or less is being carried out at IEC. In the frequency range below 150 kHz, it is necessary to take measures against noise from the fundamental wave. In this report, we describe the situations that the effect of filtering measures on frequency range and measurement conditions of 150 kHz or less and 150 kHz or more are studied.
