The ITER Pulsed Power Supply System includes the superconducting coils power supplies and the Heating and Current Drive (H&CD) power supplies. Since the early phase of the ITER EDA, it is assumed that the ITER site is supplied by a powerful High Voltage (HV) line connected to the HV Grid available in the area: the HV Grid is able to supply the estimated ITER loads. The design has progressively become more detailed and has been modified following the evolution of the Poloidal Field (PF) configuration: the Central Solenoid (CS) is layer wound, with four conductors in hand, therefore it requires to interrupt currents in the range of 170 kA at plasma initiation and for quench protection. The nine PF coils are supplied independently. H&CD methods will be selected among: Ion Cyclotron (IC), Electron Cyclotron (EC), Lower Hybrid (LH) and Neutral Beams (NB).

This paper will report the status of the design for the Final Design Report. The overall scheme will be presented from the HV line to the boundaries of the loads and the critical features of the design will be reported.

The solution identified for the interruption of current in the range of 170 kA, required by the CS design, will be reviewed: the use of parallel components is foreseen; the progress made so far on the limited R&D foreseen on switches will be reported.

The design of the NB power supply, including the main 1 MV, 46 MW DC power supply, the auxiliary power supplies with its HV deck, the transmission line, etc... will be presented and the R&D plan on the transmission line will be discussed. For the IC power supply it is expected to use a scheme known as Pulse Step Modulator (PSM), such a scheme could be used also for EC and LH power supplies.

Finally Local Energy Storage (LES) has been considered in case a candidate site does not satisfy the HV Grid assumption mentioned above. LES could be provided to smooth the large power pulses (~ 250 MW, ~ 2.0 GJ) required to control plasma perturbations such as minor disruptions, large elms, etc... The LES, foreseen so far, uses large asynchronous generators, rotor wound: two or four such machines could be required (for each: usable energy ~ 2GJ); the stator is connected directly to the AC line and the rotor is supplied through an inverter.
