What Ampegon does
Ampegon Power Electronics AG is a Swiss engineering company that designs and delivers high-power RF amplifier systems, high-voltage and high-current power supplies, pulsed power and modulator systems, and shortwave transmitters for scientific, medical, industrial, and broadcast applications. The company is headquartered in Baden, Switzerland, employs 51–100 people, and operates as a subsidiary of Italian industrial conglomerate Cocchi Technologies (formerly Aretè Cocchi Technology Group), which established the entity in 2019 by acquiring the strategic assets of the legacy Ampegon AG (originally founded in 1937). Ampegon's installed base underwrites flagship global projects including the ITER fusion program, Diamond Light Source synchrotron, Wendelstein W7-X stellarator, Australian National University fusion research, MIT, Max Planck Institute, EBG MedAustron cancer therapy center, and Radio New Zealand's TSW-2100 shortwave transmitter.
The product portfolio spans four core families: High-Power RF Amplifier Systems used to drive synchrotrons, LINACs, and free electron lasers; High-Voltage and High-Current Power Supplies for fusion heating systems (ECRH, ECCD, NBI) and plasma physics; Pulsed Power and Modulator Systems for particle accelerators; and the TSW shortwave transmitter family (50 kW to 500 kW, with TSW-2100/TSW-2300/TSW-2500 variants) supporting analogue AM and digital DRM operation. Engineering is performed in Switzerland under ISO 9001-certified processes, Ampegon is a founding member of the Digital Radio Mondiale Consortium, and the technology integrates remote diagnostics with energy-saving modes (AMC, DCC, DRM).
Ampegon executes a sales-led, direct enterprise go-to-market in which revenue is generated through custom engineered system sales (treated as one-time licensed projects) supplemented by aftermarket services spanning spare parts, control system upgrades, extended warranty, and returns/repairs across the full project lifecycle. Distribution is global with named operations in Switzerland and a parent-supported U.S. footprint in Franklin Park, Illinois. The company pursues expansion through public-fusion milestones (ITER, Alpha Alliance with Proxima Fusion), adjacent industrial applications (gyrotron-based geothermal drilling, space observation, defense), DRM-led broadcast digitization, and continued parent-group capacity buildout.
