Abstract
A design for a power supply system for the neutral beam injection (NBI ) test stand of the large helical device (LHD) is presented. The accel eration power supply of -250 kV, 50 A is composed of three power suppl ies connected in series to deliver two intermediate outputs. It has a -40 kV power supply, a - 90 kV power supply and a -120 kV power supply . A beamline and the major part of the power supply system for the NBI test stand were constructed in 1992. The -120 kV power supply was mov ed from Higashiyama to Toki in 1994. Another power supply of -40 kV wi ll be added for -250 kV acceleration in the future. A brief outline of the control system of the NBI test stand is also presented.
