“…The DC/DC converters in an aircraft require an EMI filter to filter the noise from the input to the power supply and vice versa. GaN technology can significantly reduce the size and weight of the EMI filter used in these converters [94]. Converters in the aircraft are connected to a low voltage DC bus of around 28 V. SiC devices are becoming common switch technology in MEA applications.…”

Gallium Nitride High Electron Mobility Transistors (GaN HEMTs) enable higher efficiency, higher power density, and smaller passive components resulting in lighter, smaller and more efficient electrical systems as opposed to conventional Silicon (Si) based devices. This paper investigates the detailed benefits of using GaN devices in transportation electrification applications. The material properties of GaN including the applications of GaN HEMTs at different switch ratings are presented. The challenges currently facing the transportation industry are introduced and possible solutions are presented. A detailed review of the use of GaN in the Electric Vehicle (EV) powertrain is discussed. The implementation of GaN devices in aircraft, ships, rail vehicles and heavy-duty vehicles is briefly covered. Future trends of GaN devices in terms of cost, voltage level, gate driver design, thermal management and packaging are investigated.INDEX TERMS Electric vehicle, gallium nitride, high electron mobility transistor, hybrid electric vehicle, wide bandgap devices.

One of the most challenging and interesting field in power electronics is the ability to mitigate the Electromagnetic Interference (EMI). A natural source of EMI includes the atmospheric discharge/charge phenomena and extra-terrestrial radiation. Man-made source of EMI are line radiation, auto ignition, radio frequency interference and power lines. Suppression of EMI and enhancing the Electro Magnetic Compatibility (EMC) has become essential in high frequency power electronic converters. This review article is a one stop solution for new researchers and practitioners to understand about the effects of EMI and its suppression techniques in detail. INDEX TERMS Electro magnetic compatibility, electro magnetic interference, mitigation.

“…As was discussed, a higher switching frequency reduces the mass of the converter, as smaller magnetic components and capacitors can be used, however this train of thought does not only hold for the functional components but can be extended for the filter design. However, it has also been shown that CM filter weight increases due to larger CM emissions at higher frequencies [7]. The attenuation of an EMI filter will degrade at higher frequencies due to parasitics, therefore components must be selected carefully to reduce higher frequency Conducted Emission (CE) [8], [9].…”

For space exploration, for instance by use of Cube-Sats, there is need for small converters which can both operate isolated and non-isolated with a low EMI profile. Incorporating Electromagnetic Compatibility (EMC) within the design stage is therefore crucial, and can be achieved by applying different EMI mitigation techniques from the very start of the design. This paper investigates inherent reduction of EMI via interleaving, balancing, and symmetrically designing a DC/DC converter. Mass and volume restraints are considered as well during the design. It will be shown that these relatively advanced (but matured) design techniques, already well known and utilized on Earth, can be utilized for a novel design for space based applications with beneficial charateristics.
