摘　　要：针对超导磁铁对电源的要求,提出了基于Buck Chopper电路的多相多重化的电源拓扑结构,采用IGBT为卸能开关来实现失超快速保护,分析了其工作原理。按该方案研制了一套高精度加速器超导磁铁电源,进行了严格的测试,结果表明,该方案满足了同步加速器超导磁铁对电源的高要求。Aiming at the special requirements of the superconducting magnet to the power supply,the topology of multiphase and multiple-configuration structure based on Buck Chopper in parallel was presented.The scheme adopts IGBT as the energy-discharge switch thus to achieve the fast quench protection to the superconducting magnet coils of the power supply,and the working principle was given.The high-precision power supply of accelerator superconducting magnet was designed and manufactured that has been passed the strict experimental tests.The test results show that this scheme can well satisfy the high requirements of the synchrotron superconducting magnet to the power supply.
