I I B F 2014 Fusione e ITER OCEM Power Electronics Giuseppe Taddia Italian ITER Business Forum -‐ Milano, 26 Giugno 2014 1 OCEM Since year 1943 OCEM is a world player in the engineering and manufacturing of power electronics systems for scienDfic and industrial applicaDons, and for airfield lighFng. More recently also for the railway sector and public lighFng. It is situated near Bologna, in the north of Italy. Its premises include over 5.000 square meters of producDon and tesDng area, warehouse and offices. OCEM is organized in two business units: • POWER ELECTRONICS • AIRFIELD TECHNOLOGY 2 Power Electronics Business Unit -‐ Products Power electronics solu.ons... 3 Main ApplicaFons Plasma Physics Research ParDcle Physics SuperconducDvity Biomedical Railways applicaDons Advanced Industry 4 Core competences Power Electronics! Power Supplies and solu0ons based on power electronics in different fields, with main focus on the “big physics” projects Skills: Power Electronics Controls & Interfaces Quality System Management Project Management Assistance & Maintenance 5 > 40 years of experiences in Fusion • Power Supply Systems for AddiFonal HeaFng: E C R H and Neutral Injectors • and more recently Very High Power Switching Network Units JET -‐ UK JT60 Japan FTU Italy TCV -‐ Switzerland Tore Supra France RFX Italy Recent and current experiences: • ECRH PS System for the European Test Facility for the 2 MW CPD Gyrotrons in CRPP -‐ Lausanne • Switching Network Units for the superconducDng poloidal coils of JT60SA, 4 units (ongoing) • Ion Source and ExtracFon Grid Power Supplies System for the NBI of PRIMA TF and ITER (ongoing). 6 FUSION – ITER Project 150.000.000 ⁰C → RISCALDAMENTO DEL PLASMA!

Main raDngs: 20 kA, 5 kV The switch integrates an electro-‐mechanical device and a solid state StaDc Circuit Breaker, parallel connected. The SNU resistance can be staDcally pre-‐arranged by motorized disconnectors and dynamically reduced by a solid state Making Switch.
