GigaDevice has officially announced the launch of its Digital Power Joint Lab in collaboration with Navitas Semiconductor, a leader in gallium nitride (GaN) and silicon carbide (SiC) power technologies. The partnership brings together GigaDevice’s GD32 microcontroller (MCU) expertise and Navitas’ high-speed, high-frequency GaNFast and GeneSiC semiconductor technologies to accelerate the development of advanced digital power solutions for emerging markets such as AI data centers, renewable energy, energy storage, charging infrastructure, and electric vehicles.
Before its formal launch, the joint lab achieved several notable milestones, including 4.5 kW and 12 kW server power supply designs and a 500 W single-stage photovoltaic (PV) micro-inverter, addressing the industry’s growing need for high-efficiency and high-power-density systems.
The 500 W PV micro-inverter integrates GigaDevice’s GD32G553 MCU with Navitas’ GaNFast Bi-Directional power ICs in a single-stage DC-AC conversion architecture. The design achieves over 97.5 percent peak efficiency, 97 percent CEC efficiency, and 99.9 percent MPPT efficiency, while eliminating the intermediate DC-DC stage to improve power density and reduce system cost. Magnetic integration and GaNFast technology further minimize component count and losses.
For AI computing applications, the 4.5 kW and 12 kW AI server power supply solutions combine GigaDevice’s MCU control with Navitas’ GaNSafe ICs and Gen-3 Fast SiC MOSFETs. The 12 kW model meets OCP, ORv3, and CRPS standards, achieving an exceptional 97.8 percent peak efficiency, surpassing the 80 PLUS “Ruby” benchmark for high-performance data center power.
The new Digital Power Joint Lab will focus on co-developing system-level reference designs and application-specific power architectures that integrate intelligent control, high-frequency operation, and next-generation semiconductor technologies. Through this collaboration, GigaDevice and Navitas aim to enable smarter, greener, and more sustainable power systems that support the accelerating global demand for energy-efficient digital infrastructure.
