“…However, changing the circuit topology is generally complex since the trade-offs between efficiency, cost, and EMI level need to be considered. Changes in circuit topology may improve EMI performance but could potentially lead to reduced efficiency due to increased switching losses or other factors (Yang et al, 2023;Zhang et al, 2023b;Mozaffari and Amirabadi, 2019;Chowdhury and Ahn, 2023). In addition, altering the circuit topology can impact the cost of components, manufacturing, and testing.…”

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.
