【摘要】 文章介绍了80 kV,80A EA ST托卡马克装置中性束注入器加速极电源的设计方案,该方案利用脉阶调制技术,引入一种新颖的80个不可控直流电源模块串联的解决方案;加速极电源的输出电压取决于投入的模块数,通过开关可调节输出电压在0%~100%额定电压范围内阶梯变化;与传统的整流加串联真空调整管方案相比较,该方案具有多方面的优点。更多还原

【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.更多还原
