The dream of zero-pollution commercial aircrafts may only one day become reality by a massive electrification of such flying vehicles. This is currently being done in concepts such as More Electric Aircraft (MEA), which relies on replacing conventional non-electrical aircraft systems such as pneumatic, hydraulic, and mechanical systems by electrical ones. One of the main challenges associated to the MEA is to significantly increase power density of electrical power systems, without compromising on reliability. This can only be achieved by the generalization and optimization of power converters in different applications inside an aircraft such as: pumps, fans, actuators, galleys, anti-icing systems, and others. Nevertheless, an All Electric Aircraft (AEA) will be only conceivable if extreme progress is made on power electronic technologies. The most promising technology recently introduced which is producing a real revolution on power converters and devices is the disruptive technology called Wide Bandgap (WBG) semiconductors. These components, which are either made of Silicon Carbide (SiC) or Gallium Nitride (GaN), have theoretically much higher performance than their Silicon counterparts concerning thermal aspects and switching and conduction losses. However, reliability and cost, as well as electromagnetic interference caused by such components are real issues which must be overcome so they can be effectively used in future aircrafts and launch the so-expected green revolution in transportation. The goal of the proposed Panel Discussion is to connect manufacturers of aircraft, equipment and power electronic components as well as researchers in order to discuss the current state-of-art, share new ideas and concepts, and debate about the advantages and bottlenecks of the use of such components applied to electrical aircrafts and related applications.
