摘　　要：阴极高压电源采用单相桥式整流电源模块串联的结构,通过优化的控制算法控制不可调电源模块的开通个数,实现高压输出的初步建立,再利用算法使其可调电源模块动态输出,实现快速跟踪设定值以达到高稳定度的电压波形输出。目前该80 kV/50 A/3s电源控制系统已完成输出电压、电流、电压纹波、过流保护时间等多次统计测试。测试结果表明,其在输出电压53 kV时,平顶电压纹波系数为0.57%,可满足电子回旋共振加热系统相关指标要求。The cathode high voltage power supply adopts the structure of single-phase bridge rectifier power module in series,and controls the number of non-adjustable power modules through the optimized control algorithm to realize the preliminary establishment of high voltage output,and then uses the algorithm to make the dynamic output of the adjustable power module to achieve fast tracking of the set value to achieve high stability of the voltage waveform output.At present,the 80 kV/50 A/3 s power supply control system has completed several statistical tests such as output voltage,current,voltage ripple and overcurrent protection time.The test results show that when the output voltage is53 kV,the flat-top voltage ripple coefficient is 0.57%,which can meet the relevant index requirements of the electronic cyclotron resonance heating system.
