Abstract-Electromagnetic interference (EMI) is one of the biggest challenges faced during the production of any electronic device. If the EMI profile of the system does not meet the accepted standards, then it becomes necessary to take measures to reduce the influence of these unwanted interferences so that the equipment can be used in the real world. Practical methods to control conducted and radiated emissions in DC/DC converters involve a combination of design techniques, component selection, and filtering strategies. One key approach is to identify and mitigate noise sources within the converter, such as fast voltage and current transitions, and to optimize the converter’s layout and grounding to minimize radiation. Filter design and optimization involve selecting appropriate components, such as inductors, capacitors, and ferrite beads, and configuring them to achieve the desired attenuation and impedance characteristics. Parasitic components, such as series inductance and series resistance, can have a significant impact on EMI and should be considered in simulation and design. By combining these practical methods, this paper gives designers insight on how we can effectively, control conducted and radiated emissions in DC/DC converter based designs and ensure compliance with relevant EMI standards.
