Current Status and Future Trends of GaN HEMTs in Electrified Transportation
TL;DR: The detailed benefits of using GaN devices in transportation electrification applications are investigated, the material properties of GaN including the applications ofGaN HEMTs at different switch ratings are presented, and the challenges currently facing the transportation industry are introduced.
Proceedings ArticleDOI
Estimating switching losses for SiC MOSFETs with non-flat miller plateau region
TL;DR: In this paper, the authors present a method to obtain an estimate of switching transition times and power losses, using datasheet parameters, for SiC MOSFETs with non-flat gate-plateau region.
Journal ArticleDOI
Variable-Frequency Critical Soft-Switching of Wide-Bandgap Devices for Efficient High-Frequency Nonisolated DC-DC Converters
TL;DR: Variable frequency critical soft switching control method is proposed with the constraints to maintain the maximum frequency within soft switching operation to prevent turn-on losses that are typically much larger than the turn-off losses in SiC and GaN FETs.
Proceedings ArticleDOI

TL;DR: In this article, a half-bridge DC/DC switching circuit is proposed for the balancing of lithium-ion cells, and highlights its advantages over existing cell balancing techniques, showing greater controllability and improvement in efficiency in comparison with existing systems.
Proceedings ArticleDOI
Turn-off energy minimization for soft-switching power converters with wide bandgap devices
TL;DR: This paper introduces a soft-switching technique for power converters using wide bandgap devices to replace the larger turn-on losses with smaller turn-off losses and thus reduce the power dissipation of the overall system.
