GigaDevice, a top semiconductor company known for its Flash memory, 32-bit MCUs, sensors, and analog products, has launched a Digital Power Joint Lab in partnership with Navitas Semiconductor. This collaboration brings together GigaDevice’s GD32MCU capabilities with Navitas’ strengths in high-speed, high-frequency GaN technology and its advanced GeneSiC silicon carbide tech. The goal is to develop smart, high-efficiency digital power solutions for fast-growing markets like AI data centers, solar inverters, energy storage, EVs, and charging infrastructure.
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® “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.
