| Abstract: | The paper deals with the design of the 80 kV/80 A power supply for the acceleration grids of the neutral beam injectors of the EAST tokamak.In the design,the technology of pulse step modulation is adopted and 80 uncontrollable dc choppers connected in series are utilized.The output voltage depends on the number of choppers which are switched on,and its step variation between 0~100% rated voltages can be controlled by switches.The design has some advantages by comparison with conventional dc power supply with tubes in series. |
