As energy consumption in AI servers and data centers rapidly increases, High Voltage Direct Current (HVDC) has emerged as a key direction for next-generation power system. Traditional AC/DC multi-stage architectures suffer significant conversion losses, limiting overall efficiency to around 85%, prompting the industry to accelerate its transition toward 800V (or ±400V) HVDC systems.
In response, GaNrich Semiconductor Corporation (GaNrich) announced it will launch its 1200V High-Voltage GaN (HV GaN) product series by the end of 2025. Built on GaNrich's proprietary GaN on Sapphire platform, the series features low Rds(on), high breakdown voltage, and outstanding efficiency. It is designed for data-center power management, AI server power modules, and emerging HVDC systems.
As the first global supplier offering pin-to-pin GaN replacement solutions, GaNrich enables its 1200V GaN FETs to directly replace SiC devices. Under high-frequency HVDC input operation, switching loss is reduced by 30%, gate-drive loss by 90%, and auxiliary power size by 50%. On the output side, GaNrich's 100V GaN offers more than 50% lower on-resistance compared with equivalent Si MOSFETs, offering a clear efficiency advantage.
In the medium-voltage sector, GaNrich started mass production in Q3 of its 100–200V, 1–10 mΩ MV GaN product line-up, available in multiple double-sided-cooling RQFN and DFN packages. The newly launched RQFN 5×6 device achieves leading TCR (temperature coefficient resistance) performance, delivering superior high-temperature current capability versus competing GaN and SGT MOSFET devices. Applications include HVDC power supplies, power bricks, drones, industrial automation, and robotics.
According to NVIDIA's published 800V HVDC white paper, GaN/SiC device typically follow three topologies combinations in HVDC system: 1200V+100/40V, 650V + 100/40V, and 200/150V+40V. GaNrich is currently the world's only supplier capable of delivering all device combinations through a unified product portfolio. Building on extensive expertise in GaN chip design, packaging, and system module integration, GaNrich provides a comprehensive voltage range from medium to high voltage, offering high-efficiency and miniaturized power-conversion solutions that accelerate the real-world adoption of GaN in HVDC and power system applications.
