摘要：
Negative Ion Neutral Beam Injectors ask for higher voltages than Positive Ion NBIs. Up to now, mast NBI are supplied by tetrode regulated power supplies. The demand in higher voltage makes this approach not any more feasible. The paper presents a solution based on Pulse Step Modulator (PSM) technology, rated st 350 kV and an output current of 30 A in continuous operation Due to the high output voltage, system modifications compared to existing PSM are necessary. Mainly the required voltage insulation, either far the power supply and the control need new solutions.
