Research On High-performance High Voltage Pusle Power Supply

The artice first introduced magnitude meaning of ECRH to TOKAMAK and the compose of ECRH system. Then experiment on High Voltage Power Supply was emphasized. During the research of theory,developed models of power tetrode (Y841),and then examined the control characteristics using circuit analysis software,MATLAB-Simulink. The analysis software tools was used to simulate the control system of High Voltage Power Supply and yielded coincident results. By theory analysis,proved that control system design project of High Voltage Power Supply was feasible,and provided direction for the system's experiment.In the paper,also introduced the functions of CAGE,REMOTE CONTROL and LOCAL CONTROL,and pack up the relations of all units. Through disassembling,testing and renovating the original control system,gradually resumed LOCAL,REMOTE system and CROWBAR system,at last successfully accomplished control system united experiment between REMOTE unit and LOCAL unit. Based on these results,the control system united test will meet the design and performance goals of the program. The construction of ECRH system is being completed and put into use.
