The Study of Overlaid Noise and Modeling for Two Onboard DC/DC Converters with Relative Positions

Power semiconductor switching in converters enables equipment miniaturization, leading to increased instances of multiple converters operating nearby. This results in more electromagnetic noise sources and conduction noise overlay, exacerbating electromagnetic interference and necessitating a reassessment of noise mitigation strategies. A valuable approach involves designing noise-reducing filters through simulation, offering a simplified yet accurate method. This study evaluates noise overlay from the positioning of multiple power converters, demonstrating the effectiveness of proposed simulation-based modeling considering noise overlay from the positioning.
