ABSTRACT
This paper is about the study and analysis on the effects of snubber circuits such as RLD, RCD and mixed (RLD+RCD) over the conducted ELECTROMAGNETIC INTERFERENCE on high frequency power MOSFET. In this paper for various duty cycles separation of conducted EMI is done with the help of LISN circuit. The analysis is done for various duty cycles as 0.5, 0.55 and 0.6 for a switching frequency of 50 KHz using ORCAD PSPICE software. The simulated results are then compared with respect to their duty cycle.
