Due to the nonlinear characteristic of the gas-discharge plasma and influenced of the gas pressure, outside magnetic field and state of cathode, the arc discharge process in ion sources for neutral beam injection(NBI) is difficult to be closed-loop controlled stably with the arc power supply (APS). A 5 MW-NBI APS for HL-2M tokamak based on super capacitor energy storage and switching power technology is designed, results are presented in this paper. A structure of multiple composite chopping is used on the DC/DC converter of the APS power circu...
