A design and simulation for fast corrector magnet power supply

  • 摘要: 快校正磁铁电源是光源和加速器中重要的设备。随着光源性能的提升,加速器对快校正磁铁电源的性能也提出了更高要求。为满足快校正磁铁电源性能要求和简化设计过程,开展了快校正电源控制策略和仿真研究,并提出了PI控制加二阶相位补偿的方法作为快校正磁铁电源的控制策略;利用伯德图设计快校正磁铁电源的相位补偿参数,以提高电源系统相位裕量。该方法不仅保证了电源系统工作在深度负反馈状态,而且简化了相位补偿的参数计算过程。为了验证控制策略的正确性和有效性,本文提出用压控电压源代替开关器件开展电源性能仿真的方法。仿真结果验证了上述控制策略的可行性和有效性,同时验证了上述仿真方法的有效性和高效性。
