摘　　要：介绍了一台用于重离子加速器的低压大电流电源。为满足加速器电源对降低纹波输出和提高效率的特殊要求,采用了一种全新的电源拓扑结构,即基于同步整流技术的多路移相式开关变换器。文中重点介绍了该变换器在效率和纹波抑制方面的优点,给出电路仿真和试验结果,同时总结了几点经验用于参考。A novel high-current low-voltage power supply applied to accelerator system is introduced.In order to meet the critical requirements of ripple current and efficiency, a novel topologic frame based on synchronized rectifier technology had been used in the power supply.This article mainly introduces the advantage of synchronous multi-phase DC/DC converter in decreasing ripple current and increasing efficiency and gives result of simulation and practice.In addi-tion, some practice experiences have been provided for consulting.
