The power supply will be operated with a current up to 20000 A in DC mode. It has been designed using a modular approach, with a 12-pulse input rectifier and two DC link which feeds sixteen DC/DC chopper modules in parallel connection. The conceived power supply integrates a sophisticated control and a precise current measurement chain devel-oped at CERN for the Large Hadron Collider (LHC). This paper presents the solution described in the de-sign report, the choice of the main purchased components which will lead to a final assembly and test before the end of 2016.
