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.
Epitaxial YBa2Cu3O7-delta was formed by processing of laser-ablated, fluorine-free precursor films. The depositions were conducted at room temperature in low oxygen pressure on LaAlO3(LAO) single crystal substrates. Processing was done in the same deposition chamber by heating the precursor film to reaction temperatures of 750-850degC in a reducing gas ambient, and then raising the oxygen pressure...
