Abstract

Abstract

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.
