摘　　要：为了满足ITER高压大功率整流器对控制精度、快速响应及高可靠性的要求,对控制系统进行优化设计。从同步处理、移相控制及同步触发3个关键环节对控制系统进行优化:使用直接耦合同步方法,提高同步精度,由此提高了整流器开环控制精度;基于高速cPCI总线传输控制信号及高速DSP作移相处理单元,提高了系统的动态响应特性及系统集成度;采用高同步性的光触发技术,提高了整流器的均流性能。对该控制系统做了长期测试,验证了控制系统的优良性能及高可靠性。In order to meet the requirements of the control precision and fast response and high reliability of ITER high-voltage high-power rectifiers,the design of control system was optimized. We discussed the optimization design of control system by optimizing phase reference and phase-shifting control and synchronous triggering：direct coupling synchronization improved the accuracy of synchronization and the open-loop control accuracy; the cPCI bus based control signal and high-speed DSP based phase shift process unit improved the dynamic response of the system and integration rate of system; high performance synchronization with laser trigger technology enhanced the current sharing performance of the rectifier. Long time test application to this control system verifies the excellent performance and high reliability of the mentioned control system.
