NoMIS Power has achieved its latest major milestone with an award from the U.S. Air Force Research Laboratory (AFRL) to develop rugged Silicon Carbide (SiC) power devices to support the electrical power systems of aircraft.
NoMIS Power will develop 1200 V SiC power semiconductor devices (PSDs) through the award. The focus will be on metal-oxide-semiconductor field-effect transistors (MOSFETs) with enhanced operational lifetime as well as improved on-state and off-state efficiency at operating temperatures, resulting in lower losses for power electronics engineers to manage.
Solid-state power controllers within aircraft electrical power distribution systems require low on-state losses to enable passive cooling, as well as surge current and voltage overshoot protection during system start-up and fault interrupt. The proposed 1200 V SiC MOSFETs from NoMIS Power will provide airframers and system builders/integrators with the necessary PSD chips capable of high efficiency, long short-circuit withstand time (SCWT), and operational ruggedness for nominal and transient conditions. Moreover, the 1200 V rating will not only support current-generation aircraft utilizing 270 VDC architecture, but also aircraft operating with a +/- 270 VDC (i.e. 540 VDC rail-to-rail) architecture, as well.
NoMIS Power overcomes the limitations of commercial-off-the-shelf (COTS) Si and SiC-based PSDs via a novel SiC device design that is achievable using disruptive manufacturing techniques. As a result, NoMIS SiC devices can withstand higher voltage spikes and current surges during harsh operating conditions, enabling longer power management product lifetime through superior reliability and ruggedness.
Announcing the new award, NoMIS Power CEO Dr. Adam Morgan said, “Our team is very excited to get the opportunity to support strategic groups working to improve the capabilities of our armed forces. We are confident this novel SiC device technology will also have a significant impact on other critical technology markets, such as electric vehicles and grid infrastructure. These efforts will directly support our company’s near-term product launch of next-generation SiC devices.”

Semiconductors are the linchpin to the performance, safety, and customer features of Stellantis vehicles today and in the new state-of-the-art, BEV-centric STLA vehicle and technology platforms arriving soon. As the auto industry’s demand for semiconductors accelerates, Stellantis is implementing a multifaceted strategy designed to manage and secure the long-term supply of vital microchips. Developed by a cross-functional team, the strategy was created through a rigorous assessment of customer desires for advanced technology features and a keen focus on delivering the objectives laid out in the Stellantis Dare Forward 2030 plan.
The robust strategy, which is refined continuously, includes:
- implementation of a semiconductor database to provide full transparency on the semiconductor content;
- systematic risk assessment to avoid and proactively remove legacy parts;
- long-term chip level demand forecasting to support capacity securitization agreements with chip makers and Silicon Foundries;
- implementation and enforcement of a Green List to reduce chip diversity and – in case of future chip shortages – to put Stellantis in control of the allocation; and,
- the purchasing of mission-critical parts at chip makers including a long-term securitization of chip supply.
Stellantis has started to engage with strategic semiconductor providers like Infineon, NXP® Semiconductors, onsemi, and Qualcomm to further improve its all-new, state-of-the-art STLA platforms and technologies. In addition, Stellantis is working with aiMotive and SiliconAuto to develop its own differentiating semiconductors in the future.
“An effective semiconductor strategy requires a deep understanding of semiconductors and the semiconductor industry,” said Maxime Picat, Chief Purchasing and Supply Chain Officer at Stellantis. “We have hundreds of very different semiconductors in our cars.
We have built a comprehensive ecosystem to mitigate the risk that one missing chip can stop our lines. At the same time, key vehicle capabilities directly depend on the innovation and performance of single devices. SiC MOSFETS extend the range of our electric vehicles while the computation performance of a leading-edge SoC is essential for the customer experience and safety.”
To date, Stellantis has entered into direct agreements for semiconductors with a purchasing value of more than €10 billion through 2030. The supply agreements cover a variety of vital microchips, including:
- Silicon Carbide (SiC) MOSFETS, which are fundamental to the range of EVs.
- Microcontroller Unit (MCU), a key part of the computing zones for the STLA Brain electrical architecture.
- System-on-a-chip (SoC), where performance is essential for the high-performance computing (HPC) units that deliver the in-vehicle infotainment and autonomous driving assist functions.
Semiconductors play key roles in the vehicles that are driving the Stellantis transformation into a sustainable mobility tech company, as outlined in Dare Forward 2030. This includes enabling features and functions in the BEV-native STLA global platforms (Small/Medium/Large/Frame) and the seamless connectivity, remote upgradability, and the flexible service-oriented electrical/electronic architecture that underpins the STLA Brain, STLA SmartCockpit, and STLA AutoDrive artificial intelligence-powered platforms.
