“…A high-accuracy frequency equivalent model is formed by fitting the curve with a combination of resistance, inductance, and capacitance, but the accuracy of the model decreases at very high frequencies, such as those above tens of megahertz. The finite element method (FEM) usually establishes the 3D model of each component in finite element analysis software (Chen et al, 2018;Wu et al, 2023), utilizing the finite element calculation of the software application to determine the description matrix of the device parameters and combining with the physical model to determine the high-frequency equivalent model. This method is complex, timeconsuming, and highly dependent on software and computer performance (Kumaresan et al, 2021).…”

The utilization of power electronic-based converters is gaining momentum across a wide spectrum of industries. However, modern power electronic converters operate at higher frequencies compared to conventional power electronic converters, which can lead to higher rates of change in voltage and current during phase switching, and thus potentially produce more severe conducted and radiated electromagnetic interference (EMI). Their electromagnetic compatibility (EMC) has become a critical research topic, and EMI in high-frequency power electronic-based converters is more complex than that in conventional converters. This review presents a comprehensive survey of recent advancements, EMI design, and analysis of modern power electronic-based converters, focusing on the sources and mechanisms of both conducted and radiated EMI, and mitigating techniques. This review also covers the impact of topology optimization, control strategy design, and packaging design on EMC performance. Addressing emerging EMI issues in modern power electronic device-based converters is essential for ensuring safe and reliable operations. Through strategic design optimization and the implementation of EMI mitigation strategies, modern converters can seamlessly be integrated into diverse applications, offering improved EMI performance as a hallmark of their versatility.
