摘　　要：针对传统粒子加速器直流电源功率因数低和软开关控制复杂的问题,提出了一种多重化电路拓扑结构的粒子加速器直流电源,包括依次连接的输入交流滤波电路、二极管整流电路、功率因数校正电路、H桥逆变电路、高频变压器及输出二极管整流电路、输出BUCK电路和输出滤波电路。文中详细分析了主要电路模块的工作原理,并采用SABER软件对电路进行了仿真,最后依据上述原理制作了5 kW的直流电源样机,经过实验测试,电源样机输出电压连续可调,方案可行。A multi-circuit topology DC power supply for particle accelerators is introduced,including input AC filter circuit,diode rectifier circuit,power factor correction circuit,full bridge chopper circuit,high frequency transformer and output diode rectifier circuit,output BUCK circuit and output filter circuit.The power factor correction circuit is used to control the AC current of the input AC side,which improves the power factor of the system and reduces the harmonic pollution of the power supply to the grid.High frequency full bridge chopper circuit can reduce the volume of high frequency transformer.The output stage BUCK circuit is used to control the output voltage and current,and the control scheme is simple and reliable.The multistage chopper technology can improve the requirements of power supply on output voltage ripple,power factor and power density of power module.
