Thales has developed a dedicated power module to meet the specific needs of More Electric Aircraft (MEA) and Urban Air Mobility (UAM), more notably flying taxis.
Our COTS Aero power module is a full-SiC phase leg power module suitable for all DC/AC power conversion applications up to 260kW in non-pressurised zone and at altitudes of up to 44,000 feet depending on the mission profile.
This COTS solution is compatible with DO-160 standards and combines a small form factor with robust mechanical design and high performance, in particular thanks to the use of Silicon Carbide MOSFET chips.
Its innovative packaging allows engineers to design high-performance systems that are smaller, lighter and more economical thanks to their higher power density, lower switching losses and the ability to operate at high temperatures.
Thales's COTS Aero power module offers a fast track to fully qualified and reliable onboard equipment solutions that make it possible to optimise system architecture from the earliest phases in the design process.
This new power module brings significant benefits for onboard equipment providers, lowering total cost of ownership thanks to shorter development cycles and offering greater flexibility in electrical architecture design.
