Consorzio RFX is a research organization promoted by CNR, ENEA, Padua University, Acciaierie Venete S.p.A. and INFN, under the patronage of Euratom – ENEA Association. Reversed Field eXperiment (RFX) is an experiment carried out in the facilities of Institute for Ionized Gas (IGI) of the National Research Council (CNR) in Padova. The experiment studies the confinement of a plasma for a controlled nuclear fusion, by the use of a magnetic field in a Reversed Field Pinch (RFP) configuration. Historically RFX is a step forward in the RFP configuration to higher plasma currents. EEI supplies to RFX experiments includes four power supply units DC bus, each of them containing four section, for a total of:

• 48 DC/DC Chopper
• 48 Magnetic Coils

Main features of the equipment are:

• Synchronized supply of coils creating a rotating corrective field.
• High flexibility in coordination and control, DSP based, with fiber optical signals transmission
• High dynamic DC/DC converters with a current of 450A at 400V, with a control time of 100ms
• Large capacitive energy storage of 1F for each 12 DC/DC group.
