| Abstract: | The high power pulsed magnetic power supply system of HL-2A is introduced in this paper.HL-2A is the first large Tokamak device with diverter in China.The main circuit of power supply is made up of pulsed generators with flywheel,rectifier transformers,thyristor converters,diode rectifiers and switches.Many key technologies such as output balance technology of two generators with diode rectifiers paralleled directly,current balance technology of paralleled rectifiers,constant-angle phase shift control technology which is adequate for dynamic change in large frequency range,all-turn-off detection of six-phase rectifier with high current,advanced monitoring system and measurement of pulsed high voltage and high current are adopted in HL-2A power supply system.The experimental results show that the performance of power supply can satisfied the requirement of experiment very well. |
