The Improvement of Capacitor Bank of HL-2A Tokamak

摘要

There are two kinds of charging mode of the ohm power supply. When the device works normally and the plasma breakdown voltage is low, the ohm power supply will run in the logical non-loop current mode which current is symmetrical, but when the discharging condition is not very well and the plasma breakdown voltage is high, the unsymmetrical mode will be adopt, i. e. switching off the positive rectifier,
