Dear Colleagues,

Power electronics has emerged as an enabling technology in the deployment of next-generation sustainable systems including transportation systems, motor drives, robotics, biomedical applications, renewable energies, smart grids and data centers. The sustainable transportation segment of power electronics requires novel power conversion systems to meet stringent requirements in terms of cost, weight, volume, power quality and reliability. It is highly challenging to enhance all these performance metrics simultaneously in a single design. The advent of wide bandgap (WBG) power semiconductors (such as SiC, GaN) caused a paradigm shift in power electronics design through enabling the converters to switch at a high frequency while maintaining a high-temperature, high-density and highly efficient power conversion. The wideband gap device technology development and its application in the transportation sector is a wide-open area for power electronics research. Moreover, to realize the advantages of high-frequency WBG power electronics in transportation electrification in practice, research and development activities in different areas need to be carried out to specifically address the open-end design problems. Some of the critical areas are (a) innovative power converter topologies, (b) novel design approach for high-frequency magnetics design with minimized parasitics, (c) high-density electromagnetic interference (EMI) filter design methodologies, (d) magnetic coil design and optimization for wireless power transfer, (e) performance evaluation of WBG devices in high-temperature (>200^oC) power conversion and (f) high-performance time-optimal control schemes for power converters.

The main aim of this Special Issue is to seek high-quality submissions that highlight the emerging applications of high-performance power converters in sustainable transportation systems. The topics of interest include, but are not limited to:

• Onboard and offboard charging systems for electric vehicles;
• Aspects and challenges of cybersecurity in EV charging systems;
• Wireless power transfer for EV charging;
• Power electronics for more electric aircrafts (MEA);
• Power electronics for electric ships;
• Power electronics for mobile robots;
• Traction inverters and powertrain systems for electric vehicles.
