Before its official launch, the lab achieved several important technological milestones, including 4.5kW and 12kW server power supply solutions and a 500W single-stage PV micro-inverter, addressing the industry's demand for high-density, high-efficiency power design and demonstrating the combined innovation strength of both companies.

-- The 500W single-stage PV micro-inverter solution, powered by GigaDevice's GD32G553 MCU and Navitas' GaNFast? Bi-Directional power ICs, adopts a single-stage one-to-one architecture, offering high efficiency, low loss, high integration, and cost optimization. Through an advanced hybrid modulation strategy and soft-switching techniques, it achieves over 97.5% peak efficiency, CEC efficiency above 97%, and MPPT efficiency exceeding 99.9%. The single-stage architecture directly converts DC to AC, removing the intermediate DC-DC stage, improving power density while reducing components and system loss. Magnetic integration and GaNFast? Bi-Directional power ICs further minimize system size and BOM cost.

-- The 4.5 kW and 12 kW AI server power solutions, developed with GigaDevice's GD32G553 MCU alongside Navitas GaNSafe? ICs, and Gen-3 Fast SiC MOSFETs, target AI servers, conventional servers, and hyperscale data centers. The 12kW model complies with OCP, ORv3, and CRPS standards, through a compact, optimized design, surpasses the 80 PLUS(R) "Ruby" efficiency benchmark, reaching 97.8% peak efficiency.

With the establishment of the Digital Power Joint Lab, GigaDevice and Navitas will further expand their collaboration to accelerate innovation in next-generation digital power systems. The lab will focus on developing comprehensive system-level reference designs and application-specific solutions to enable smarter, greener, and more energy-efficient power systems across data centers, renewable energy, and electric mobility. This partnership marks a significant step toward shaping the future of digital power electronics through technology integration, innovation, and sustainability.
