The preliminary design for ITER AC/DC converters under the responsibility of the Korean Domestic Agency is performed on the basis of the engineering experience of previous R&D for a full-scale 6-pulse CS (Central Solenoid) converter unit. This paper describes key features of the preliminary design for the respective sub-systems; integrated self-supporting aluminium structure and symmetrical thyristor...
The ITER Power Supply it will be the largest ever built in terms of power, pulse length, and energy capacity. It will also be responsible for fast discharge of the ITER superconducting magnets whose energy storage will be at an unprecedented scale. Nearly all of the components that comprise the system will be unique, custom designed items that will exceed the prior state of the art. This paper describes...
The ITER Coil Power Supply and Distribution System (CPSDS) will be installed to receive power from the French 400 kV transmission grid and to provide controlled DC power to the superconducting tokamak magnets for plasma operation.
The ITER Pulse Power Electrical Network (PPEN) is capable of supplying 500 MW of pulse power and to compensate 750 Mvar of reactive power. In addition, the AC/DC conversion plant is always operated in dynamic conditions in terms of plasma control requirements. The AC/DC converter power supplies produce numerous harmonics, and with the large installed power compared to short circuit capacity and complex...
The paper gives a description and key design features for the EAST power supply system consisting of superconducting coil power supply, inner vessel coil power supply, and additional heating power supply including microwave power supplies and neutral beam injection power supply. These power supplies are all realized by AC/DC converter, H Bridge and IGBT chopper.
In this paper, firstly, ITER power supply and its AC/DC converter in 2001 design have been introduced. Some import criteria such as FSC and internal bypass are reviewed and researched. The system overvoltage and low frequency oscillation have also been studied. Then some proposals to improve the ITER design and baseline have been presented, and these proposals have been validated and supported by...
