MINYSA ADVANCES SWISS GAN CHIPS FOR SPACE POWER SYSTEMS

At Microcity Neuchâtel, Minysa is developing GaN gate-driver ASICs and power-control ICs designed to make space and other high-reliability power systems smaller, cooler and more reliable. 

«Microcity gives Minysa the right environment to grow: proximity to microtechnology expertise, research capabilities, industrial partners and a deeptech ecosystem that understands semiconductor innovation. This setting helps us turn Swiss GaN power electronics into real opportunities for space and other high-reliability markets.»

Power electronics is a quiet but critical building block of modern technology. It controls, converts and distributes energy in satellites, robots, electric drives, drones, data centres and industrial systems. As these systems become more compact, autonomous and power-hungry, they also need electronics that are smaller, lighter, more efficient and more robust. This is where Minysa comes in. Founded in Neuchâtel in 2025, the semiconductor startup develops highly reliable GaN gate-driver ASICs, power-control ICs, system-in-package solutions and power modules for demanding applications. 

Gallium nitride, or GaN, enables higher switching speeds, greater power density and lower heat generation than conventional silicon-based power electronics. But broader adoption remains technically demanding: gate drivers, protection functions, sensing, monitoring, layout and qualification all need to work together precisely. Minysa addresses this integration challenge by developing ultra-fast gate-driver and power-control chips that help manufacturers reduce design risk and use GaN power semiconductors more safely, efficiently and compactly. 

An important milestone has now been reached: Minysa has received CHF 150,000 from Venture Kick to accelerate development of its GaN gate-driver ASICs for space and other high-reliability applications. The company already reports an active pipeline with four space customers and two ESA-funded programmes focused on customised power-management chips for power conversion systems and compact motor drives. This positions Minysa in a strategically important field where performance, reliability and technological sovereignty are increasingly linked. 

Minysa is based at Microcity Neuchâtel, part of Switzerland Innovation Park Network West EPFL. For a semiconductor startup, this environment provides proximity to research, specialised talent, microtechnology expertise, industrial partners and a network that can support deeptech projects from chip architecture toward customer-specific applications and market orientation. With Venture Kick support and its roots in the Microcity and Switzerland Innovation ecosystem, Minysa is working toward a clear ambition: to become a Swiss semiconductor reference for sovereign space power electronics, with future relevance for robotics, drones, industrial drives, e-mobility, renewable energy and AI infrastructure.
