Navitas-GigaDevice Digital Power Lab Launches, Surpassing 97.8% Efficiency in AI and Renewable Power Solutions

Collaborative Milestone: Industry-Leading Efficiency in Power Management

Navitas Semiconductor (NASDAQ: NVTS) and GigaDevice have officially launched a Digital Power Joint Lab, unveiling next-generation power solutions targeting AI data centers, photovoltaic inverters, energy storage systems, EV charging infrastructure, and more. The lab, a union of GigaDevice’s microcontroller expertise and Navitas’ high-frequency GaN and SiC power technologies, aims to meet growing demand for smarter, more efficient digital power systems across high-growth sectors.

Technical Highlights: Server Power Supplies Reach 97.8% Peak Efficiency

Among its achievements, the lab introduced advanced AI server power solutions with efficiency numbers that push industry boundaries. Notably, a 12 kW power supply for hyperscale data centers surpasses the 80 PLUS "Ruby" standard, recording a 97.8% peak efficiency, while remaining compact and compliant with leading standards (OCP, ORv3, CRPS).

The following table summarizes the lab's technical achievements:

Product Innovations: Streamlined Designs and Cost Optimization

Engineered for the modern energy landscape, the lab's solutions deliver substantial improvements in system efficiency, density, and component reduction. The 500W single-stage PV micro-inverter utilizes a direct DC-AC conversion architecture, bypassing an intermediate stage, which translates to fewer components, minimized system losses, and lower BOM cost—all while achieving over 97.5% peak and 99.9% MPPT efficiency.

Magnetic integration and the use of GaNFast bi-directional ICs are crucial to reducing both physical footprint and cost. Meanwhile, advanced hybrid modulation strategies and soft-switching technology are credited for these impressive efficiency metrics.

Implications: Positioning for a Greener, More Efficient Future

This collaboration highlights a strong shift toward highly efficient, scalable power management systems at a time when demand from AI, renewable energy, and electric mobility is set to accelerate. By delivering reference designs that break efficiency records and minimize cost, Navitas and GigaDevice are laying the groundwork for broader industry adoption and setting new benchmarks in sustainability-focused innovation.

Key Takeaway: Industry Leadership Through Integrated Innovation

For stakeholders across AI data centers, renewable infrastructure, and automotive applications, these technical milestones from Navitas and GigaDevice suggest the possibility of deploying power systems that are not only smaller and more cost-efficient, but also achieve best-in-class energy performance. As the lab pushes toward more comprehensive, system-level reference designs, the potential market impact—particularly in the face of growing demands for smarter, greener energy—will be one to watch.
