The control system of the 100kV HVPS for NBI

A 100kV/100A High Voltage Power Supply (HVPS), which will provide the energy for 4MW ion source of the neutral beam injection (NBI), has been developed in Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). The power supply is based on the technology of pulse step module (PSM)[1] which consists of many DC chopper module with the same configuration.
