Guest Editorial: Resilient and Compact Powertrains for On-the-Move Electrical Energy Technologies

The articles in this special section focus on resilient and compact power trains for on-the-move electrical energy techniques. On-the-move electrical energy technologies typically operate off the grid with no or minimal interaction with the utility network. These systems should therefore be light and compact to minimize power consumption and increase the operational time in transportation applications. They often have resilient structures because of rapidly changing environmental conditions, and the fact total failure in some systems might be catastrophic. To reduce the cost and enhance the performance of electrical energy technologies for transportation electrification, such as more electric aircraft, electric vehicles, drones, and robots, the industry is moving toward applications with more power electronics. High power density and resilient converters are critical enablers for the transportation industry to unlock significant improvements in system weight, energy consumption, total life-cycle costs, maintainability, and overall system reliability.
