GigaDevice has announced the official launch of its Digital Power Joint Lab in partnership with Navitas Semiconductor. The initiative combines GigaDevice’s GD32 microcontroller expertise and Navitas’ gallium nitride (GaN) and GeneSiC silicon carbide technology, aiming to develop intelligent, high-efficiency digital power solutions targeting data centers and other emerging applications.
According to GigaDevice, the joint lab has already developed 4.5 kW and 12 kW power supply systems for servers, as well as a 500 W single-stage photovoltaic (PV) micro-inverter prior to its formal launch. The data center-focused 4.5 kW and 12 kW server power solutions use GigaDevice’s GD32G553 MCU, Navitas GaNSafe ICs, and Gen-3 Fast silicon carbide MOSFETs. The 12 kW model is designed to meet Open Compute Project (OCP), Open Rack Version 3 (ORv3), and Common Redundant Power Supply (CRPS) standards. GigaDevice reports the solution delivers a compact, optimized design and achieves a 97.8 percent peak efficiency, exceeding the 80 PLUS “Ruby” efficiency threshold.
In the renewable segment, the 500 W single-stage PV micro-inverter uses the GD32G553 MCU and Navitas GaNFast Bi-Directional power ICs in a one-to-one architecture. GigaDevice says this system achieves over 97.5 percent peak efficiency, with California Energy Commission (CEC) efficiency above 97 percent and maximum power point tracking (MPPT) efficiency exceeding 99.9 percent. The direct DC-to-AC conversion architecture removes the need for an intermediate DC-to-DC stage, increasing power density and reducing both system size and bill-of-materials costs.
The Digital Power Joint Lab plans to continue delivering reference designs and application-specific solutions for data center infrastructure, renewable energy, and electric mobility systems.
