Abstract :
The ITER pulsed power supply system includes the superconducting coils power supplies and the heating and current drive power supplies. After a short introduction the paper reports the interruption of very high current (170 kA) for the central solenoid, which is a critical issue, and other aspects of the design not described previously: the high voltage power supply (1.0 MV) for the neutral beams and the pulse step modulators for the ion cyclotron power generators. Finally the paper presents the work done on local energy storage that could be required at a site with limited power capability
