Wise Integration, Powernet and KEC sign MoU to co-develop SMPS solutions for AI server power supplies in Korea
Fabless company Wise Integration of Hyeres, France, together with switched-mode power supply (SMPS) manufacturer Powernet Technologies Corp and power semiconductor firm KEC Corp (both of Seoul, South Korea), have signed a strategic memorandum of understanding (MoU) to co-develop next-generation SMPS solutions designed specifically for AI server applications in South Korea. The partnership aligns with the South Korea’s push to expand AI infrastructure and build out the next generation of high-density data centers.
Wise Integration will supply its gallium nitride (GaN) power devices, digital-control expertise and technical support. Powernet will lead development of new SMPS designs using Wise’s WiseGan and WiseWare technologies. KEC will manage back-end manufacturing, including module integration and system-in-package production tailored to the thermal and reliability demands of AI server racks.
In addition to accelerating the design and development of competitive AI server power supply solutions and creating business opportunities in Korea’s AI server market, the project aims to shorten the solutions’ time-to-market using WiseGan and WiseWare technologies. The collaboration builds on an earlier partnership between Wise Integration and Powernet, launched to serve OEMs that require compact, digitally controlled power supply systems for faster, smaller and more energy-efficient electronic equipment.
AI servers draw extensive power, generate intense heat, and depend on SMPS designs capable of converting high-voltage input (e.g. 400V) to stable 48V rails with minimal loss. GaN devices with digital control are uniquely suited for that task: they enable higher switching frequencies, greater efficiency, and more precise management of fast, high-current load transients.
Supporting South Korea’s national ambition
The South Korean government’s investments in AI-dedicated data centers includes high-performance GPU clusters and digital infrastructure that supports demand for more efficient, compact and scalable power conversion systems.
“Korea is moving quickly to build the next generation of AI data centers, and power architecture is a critical piece of that effort,” says Wise Integration’s CEO Ghislain Kaiser. “Working with Powernet and KEC lets us bring GaN-based digital control into server-grade designs at scale — delivering the efficiency, thermal performance, and responsiveness that modern AI hardware depends on.”
Technology momentum: a logical extension of Wise Integration’s roadmap
Beyond the MoU, Wise Integration has been widening the foundation that supports strategic partnerships. As Korea accelerates AI-ready data-center development, the demands on power conversion systems intensify — higher switching frequencies, tighter thermal budgets and more aggressive efficiency targets. To meet those constraints, Wise has been expanding its GaN + digital control portfolio, ensuring that the technologies Korea aims to deploy at scale already have a maturing, production-validated base behind them.
For example, the company recently launched WiseWare 1.0 for totem-pole PFC and LLC topologies, its newest fully digital controller. While aimed currently at gaming, displays and industrial systems, it shares the same architecture — high-frequency GaN operation, compact form factor, digitally managed efficiency — that naturally scales into the server-class designs targeted under the Korea-focused collaboration.
