Abstract: Huge dv/dt and di/dt due to high switching frequency and ripples present in AC-DC converter infallibly introduce unwanted Electromagnetic Interference (EMI) noise voltage through parasitic/distributed parameters of the DC source. In this paper, the entire test setup for conducted emission (CE) is made to measure the conducted voltage disturbance of Equipment Under Test (EUT) due to various DC sources with different percentage ripple factors used to supply. The measurement carried out in the frequency band 150kHz to 30MHz as per CISPR 11 [2]/CISPR 22 [1]. The dominated DC source responsible for the significant conducted voltage disturbance measurement results are analyzed and to mitigate the conducted emission manoeuvring based on DC source is proposed. Practical measurement are used to validate the mitigation method. [ABSTRACT FROM AUTHOR]
