The Residual Ion Dump Power Supply (RIDPS) is part of the Ground Related Power Supplies (GRPS) of the MITICA experiment of the ITER Neutral Beam Test Facility (NBTF) and the two ITER Heating Neutral Beam Injectors (HNBI). The GRPS will be manufactured by OCEM Energy Technology s.r.l. (OCEM) via a procurement contract with F4E. The RIDPS is devoted to feed the electrostatic Residual Ion Dump (RID), which deflects and collects the beam residual ions after the neutralization process. The maximum average voltage of the RIDPS is 25 kV, to which can be superimposed a sinusoidal or trapezoidal alternate voltage at 50 Hz, 5 kV maximum. The nominal current is 60 A, with a maximum pulse length of 1 h. This paper describes the detailed design of the RIDPS, highlighting its peculiar aspects, and the expected performance resulting from simulations.
