| Abstract |
Feasible solutions for a power supply for dipole magnets of medical particle accelerator are invvestigated. Switching and thyristor converters are compared. Physical constraints dictate converter ratings being in the range 0-1500V, 0-3000A, 2 seconds cycle, maximum current error less then 1A. A thyristor solution, with particular care in the design of the feedback is proposed, and benefits and drawbacks are analyzed. A non-conventional control technique for thyristor converters is also investigated which uses multilevel approach to control thyristor bridges. Simulmation are presented showing the feasibility of the new control technique. |
