TPX power supply design and performance
- Princeton Plasma Physics Lab., NJ (United States)
TPX will utilize a combination of new and existing AC/DC converter equipment, the latter consisting of the inventory of equipment available at the PPPL site when TPX succeeds TFTR. To make best use of existing facilities, the TFTR (a.k.a., Transrex) converters are applied to the TPX duty when appropriate, but in general the pulse rated, high voltage converters do not match the long pulse, low voltage demand of the load during the plasma burn phase. In the Poloidal Field (PF) system the Transrex converters are suitable for the dynamic operation associated with plasma ramp up and ramp down, but are not well suited to the quasi-steady conditions during plasma burn. In this case a parallel combination of the Transrex converters with new high current, low voltage power supplies is proposed. In the Toroidal Field (TF) system a new dual voltage converter using AC bus transfer is proposed. In the Fast Plasma Position Control (FPPC) system an anti-parallel 12-pulse arrangement of Transrex converters is proposed. This paper presents a description of the design of the converter systems along with preliminary results of simulation studies of the AC/DC converter performance in terms of short circuit, voltage drop, and control.
