同步加速器二极磁铁电源的研究

Research and design of power supply for synchrotron dipole magnet

提出了一种基于晶闸管相控整流器和IGBT脉宽调制的(PWM)变换器技术的同步加速器二极磁铁电源设计方案,分析了其工作原理。试验结果表明,该方案满足了CSR同步加速器二极磁铁对电源的极高要求。

Based on phase-control thyristor rectifier and IGBT pulse-width modulation（PWM）converter, the design of power supply synchrotron diople magnet is presented. The main circuit and control scheme of power supply which make the actual current follow its value almost without tracking error are analyzed. The experimental results show that power supply satisfies the extremely high desires of the sychrotron dipole magnet.
