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,开展了快校正磁铁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,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。The power supply for fast corrector is an important type of equipment in light sources and accelerators.With the improvement of the performance of the light source,the accelerator has put forward higher requirements for the performance of the fast corrector and their corresponding power supply.To meet the requirements of the power supply for fast corrector and simplify their design process,the research of control strategy and simulation about power supply for the fast corrector is conducted.This paper proposes a way which uses the PI control plus second-order phase compensation as the control strategy of the power supply for fast corrector.For improving the phase margin of the power supply system,Bode diagram is used to design the phase compensation parameters of the power supply fast corrector.This method not only ensures that the power supply system works in the deep negative feedback state,but also simplifies the process of parameter calculation about phase compensation.To verify the correctness and effectiveness of the control strategy,this paper proposes a simulation method based on the transfer function of switching power supply which uses voltage-controlled voltage source instead of switching devices.The simulation results verify the feasibility and effectiveness of the above control strategies,and verify the effectiveness and efficiency of the above simulation methods.
