Symmetry and Duality in Electromagnetic Technology for Power Converters

Dear Colleagues,

As power electronic systems continue to develop toward higher frequency and power density, high-frequency electromagnetic coupling effects inside power converters become increasingly prominent. Symmetry and duality theories are widely applied in circuit topology design, high-frequency magnetic component design, and electromagnetic interference optimization. The design of high-frequency magnetic components, electromagnetic interference suppression, and electromagnetic sensing technologies constitute the core bottlenecks that determine system performance, operational reliability, and electromagnetic compatibility. This Special Issue focuses on high-frequency electromagnetic technologies in power converters. It welcomes original research papers and review articles on power converter topologies and modulation strategies, high-frequency magnetic technologies for power electronics, electromagnetic compatibility diagnosis and suppression, and electromagnetic sensors.

Under high-frequency operating conditions, factors such as magnetic material properties and winding parasitic effects significantly affect converter efficiency and operational stability. Conducted and radiated electromagnetic interference generated by the high-speed switching of power semiconductor devices induces complex multi-field coupling problems, imposing higher requirements on EMI mechanism modeling, noise diagnosis, and suppression. Meanwhile, as the core unit for electromagnetic signal perception, electromagnetic sensors can measure key parameters such as the voltage and current of power converters, providing fundamental support for system condition monitoring and closed-loop control. Leveraging the design philosophy of symmetry and duality is expected to further improve the efficiency, power density, and electromagnetic compatibility of power converters, as well as the measurement accuracy of electromagnetic sensors.

This Special Issue welcomes contributions covering high-frequency magnetic component design and loss modeling, parasitic parameter extraction, EMI test diagnosis and suppression schemes, novel electromagnetic sensors, and electromagnetic optimization of power converters. Studies combining theoretical modeling, simulation analysis, and experimental verification are encouraged. From the perspective of symmetry and duality, this Special Issue aims to clarify the core mechanisms, theoretical models, and optimization methods in high-frequency electromagnetism, magnetic components, EMC, and electromagnetic sensing, to provide theoretical support and technical references for the research and development of high-performance power converters.
