Special Issue Information

Dear Colleagues,

Wide-bandgap (WBG) semiconductors like silicon carbide (SiC) and gallium nitride (GaN) have transformed power electronics by facilitating better efficiency, faster switching speeds, and increased power density, which are essential for modern energy systems. To achieve the full potential of WBG devices, advanced passive components, particularly inductors, must be developed as they are crucial in power conversion systems. Conventional inductor designs are optimized for silicon (Si)-based devices and often fail when used with WBG semiconductors due to challenges such as high-frequency losses, thermal management issues, and size constraints.

This Special Issue will focus on recent advancements in inductor design for WBG devices, emphasizing the key challenges and opportunities in this field. It will highlight the integration of inductors with WBG-based power converters for various applications, including electric vehicles (EVs), renewable energy systems, switching-mode power supplies (SMPSs) for medical devices, and energy storage. By bridging the gap between WBG semiconductor technology and passive component design, this Special Issue aims to promote the development of more compact, efficient, and reliable power electronics systems.

High-resistance faults on the DC lines of multi-terminal VSC-HVDC grids lead to insufficient protection reliability, and the introduction of current-limiting strategies alters the system’s intrinsic fault characteristics, degrading protection performance. To address these issues, we propose a DC-line protection scheme that is immune to converter control strategies and highly tolerant to fault resistance. First, based on the grid topology, post-fault current paths are analyzed, and the fault characteristics produced solely by the fault-induced voltage source are identified. A sequential overlapping derivative transformation is then employed to magnify the discrepancy between internal and external faults, forming the core of the fault-identification criterion; the zero-mode component is used for pole selection. Finally, a four-terminal VSC-HVDC model is built in PSCAD/EMTDC version 4.6.2 for validation. Simulation results show that, after applying the current-limiting strategy, the characteristic quantity changes only marginally, and the proposed protection can reliably withstand fault resistances of up to 700 Ω.
