Japan Atomic Energy Agency as the JApan Domestic Agency (JADA) for ITER and the Domestic Agency of EU (EUDA) agreed the procurement sharing for the ITER NBI power supply system. The JADA contributes procurement of dc-1 MV ultra-high voltage (UHV) components such as a-1 MV dc generator, a transmission line and a-1 MV insulating transformer. The dc UHV(More)
Major issues of NBI power supplies are a high-speed switching, regulation and transmission of dc ultra high voltage, and suppression of surge energy input to the beam source at breakdown. A GTO(gate turn off thyristor) inverter type power supply where the control is performed at low voltage ac side was designed for the ITER NB. Based on the remarkable(More)
