Abstract:In HL80 constant current source, a closed-loop negative feedback and real time serial linear adjustion circuit is adopted for the control of the output current. Triphase AC voltage-modulation module is used to modulate the primary voltage of the transformer. The combination of PLC and touch-screen actualize the graphical interactive operation interface. The communication and control in HL80 is based on ethernet networks. As the load is changed from 2.0 to 3.0 Ω and the output current is changed from 20 A to 80 A, the voltage drop of the modulation transistor is controlled as 8 V±2 V, the precision of the output current is better than 0.12%, the ripple factor is lower than 0.11%. HL80 has been tested more than 10 000 shots without failure.
Keywords:constant current source  computer-control  low ripple factor  high current  linear induction accelerator
