摘　　要：在建的西安质子应用装置是一种用于空间质子辐照效应研究的装置,注入凸轨电源是其同步加速器注入系统的关键组件.该电源属于快脉冲电源,其下降电流的可控性、精确性对质子束注入效率及束流品质具有重要影响.为满足加速器小型化在该领域的需求,凸轨电源采用了一种IGBT线性工作的方案,其较大的电流变化率使电流的下降波形存在一定的非线性变化,跟踪误差也随之变大.为了实现下降电流既快又准的控制目标,本文通过调整给定数据的方式对电流波形进行校正实验,并获得了一套切实有效的电流波形校正方法.The Xi’an proton application facility (XIPAF) which is under construction is a device for the study of space proton irradiation effects. The injection bump (BUMP) power supply is the key component of its synchrotron injection system. This power supply belongs to fast pulse power supply. The controllability and accuracy of its drop-out current have an important influence on the quality and injection efficiency of proton beam. In order to meet the demand of accelerator miniaturization, an IGBT linear operation scheme is adopted for convex rail power supply, the power supply^ large current change rate makes the drop current waveform have some non-linear changes, and the tracking error also increases. Current waveform correction experiments are carried out by adjusting the given data for achieving the goal which is to control the down current fast and precisely, and a set of practical and effective current waveform correction methods is also obtained.
