Airbus and ST team up on power electronics for aircraft electrification

The collaboration builds on evaluations already conducted by both companies to explore the benefits of wide bandgap semiconductor materials for aircraft electrification. Wide bandgap semiconductors like SiC and GaN have superior electrical properties compared with traditional semiconductors like silicon. They enable the development of smaller, lighter and more efficient high-performance electronic devices and systems, particularly in applications requiring high power, high frequency, or high-temperature operations.

“This collaboration with STMicroelectronics, a global leader in power semiconductors and wide bandgap technologies, will be key to support Airbus’ electrification roadmap,” says Sabine Klauke, Airbus Chief Technical Officer, in a press release. “Leveraging their expertise and experience in power electronics for automotive and industrial applications with our own record in aircraft and VTOL electrification will help us accelerate the development of the disruptive technologies required for the ZEROe roadmap and CityAirbus NextGen.”

The cooperation will focus on developing SiC and GaN devices, packages, and modules adapted for Airbus’ aerospace applications. The companies will assess these components by conducting advanced research and tests on demonstrators, such as e-motor control units, high and low-voltage power converters, and wireless power transfer systems.

“We already have a strong, transformational presence in mobility and industrial applications, reinforced by a vertically integrated global SiC supply chain, to support our customers globally with electrification and decarbonisation,” says Jerome Roux, President, Sales & Marketing, STMicroelectronics, and continues.. “Aerospace is a highly demanding market with specific requirements. Cooperating with Airbus, a global leader in this industry, gives us the opportunity to define together new power technologies the industry needs to realise its decarbonisation goals.”
