JAEA, as a domestic agency of Japan (JADA) for ITER, is carrying out a research and development of a high-energy neutral beam injector for heating and current drive of ITER plasma in collaboration with European Domestic Agency. JADA will provide ultra-high voltage DC power supplies which can generate -1 MV DC power for the negative ion beam source. Present status of the design and manufacturing technology R&D on the power supply is reported as a part of contribution by JADA for the ITER Neutral Beam Injector. In particular, the current presentation highlights R&D status regarding the ceramic insulation tubes for water choke and the DC -1 MV insulating transformer.
