Abstract

This paper compares different topologies of DC-DC converters for levels of mitigation of EMI using a RCD snubber for each. This paper proposes the design and simulation of a Buck, Cuk and the Boost converter using the software PSPICE. The circuit was constructed on PSPICE and the output voltage of the converter is simulated for different switching frequency. The simulated output was then studied for different switching frequencies keeping duty cycle constant, and EMI was found in the output due to switching of the MOSFET. In order to minimize this interference a RCD snubber circuit was designed in PSPICE across the MOSFET of the converter. The output and simulations of these three topologies were then studied in comparison to the output of these converters without snubber circuit.
