Navitas and BrightLoop Collaborate to Advance Hydrogen Fuel-Cell Charging for Heavy-Duty Agricultural Transport

Navitas Semiconductor has announced a strategic collaboration with BrightLoop to power the next generation of hydrogen fuel-cell chargers, integrating Navitas’ automotive-qualified Gen 3 Fast (G3F) Silicon Carbide (SiC) MOSFETs. These advanced power components will support BrightLoop’s latest high-performance systems tailored for demanding agricultural and heavy-duty transportation applications.

BrightLoop is recognized for its state-of-the-art power conversion solutions that achieve exceptional performance benchmarks, including conversion efficiencies exceeding 98%, power densities up to 35 kW/kg, and volumetric efficiencies reaching 60 kW/L. Their high-voltage, high-power multiverters, when combined with BrightLoop’s proprietary Power Flow Processor technology, are engineered to deliver exceptional versatility and performance in both AC and DC domains. These systems address critical energy management requirements in hydrogen fuel-cell infrastructure, heavy-duty machinery, and high-voltage (HV) network adaptation.

At the heart of this collaboration is BrightLoop’s 250 kW HV-DC/DC converter, featuring an output of 950 VDC at 480 A, which leverages Navitas’ G3F SiC MOSFETs. The converter design is scalable, with modules that can be paralleled to reach megawatt-level power, offering a robust solution for high-load applications in electrified agriculture and transportation.

Navitas’ Gen 3 Fast SiC technology benefits from over two decades of Silicon Carbide R&D leadership and is based on proprietary trench-assisted planar technology developed under the GeneSiC brand. This platform ensures superior performance across temperature ranges, delivering efficient, high-speed switching with cool operation—ideal for applications requiring both high power and long-term reliability.

The G3F SiC MOSFETs stand out by achieving significantly lower power losses over the entire operating range. Their optimized RDS(ON) characteristics remain stable even at high temperatures, offering up to 20% lower on-resistance compared to competitive solutions under real-world conditions. These MOSFETs can reduce case temperatures by as much as 25°C, resulting in a lifespan that is up to three times longer than other SiC devices on the market.

Additionally, GeneSiC SiC devices boast industry-leading ruggedness with the highest-published, 100%-tested avalanche capability, up to 30% longer short-circuit withstand duration, and tight threshold voltage variation, making them highly suitable for paralleling in high-reliability systems. Together, Navitas and BrightLoop are setting new benchmarks in the field of hydrogen fuel-cell energy conversion, pushing forward the electrification of heavy-duty, off-road transportation with efficient, high-performance, and scalable power solutions.
