| Popis: | This critical analysis offers a comprehensive overview of the efficiency and noise reduction methodologies applied in switch mode power supplies (SMPSs) and the emerging trends in the field. The study acknowledges that power supplies are an essential element in most electronic devices, and the recent developments have placed a greater emphasis on precision, miniaturization, and effectiveness of these components. The research focuses on SMPSs in comparison with other power supply methodologies and investigates the identification and mitigation of internal and external noise in DC Buck converter design through simulations. The study explores the latest and established technologies employed in improving SMPSs' power supply units and achieving maximum performance. The paper highlights the use of a Linear Impedance Stabilization Network (LISN) topology and filter topologies to stabilize and eliminate noises in non-ideal scenarios, starting from an ideal buck converter. The research also emphasizes the design, analysis, and implementation of energy-efficient switch mode isolated converters commonly used in everyday life. Therefore, the study concludes that the integration of the LISN methodology in SMPSs design can play a crucial role in achieving maximum performance and efficiency. Comment: This study focuses on the design of LISN model to reduce output noise from traditional SMPSs used with non-ideal components. A traditional DC/DC buck SMPS was employed, and filters were designed using LISN to suppress SMPS noise. Simulation results demonstrate that the designed filter significantly reduced SMPS output noise when compared to initial and final observations |
