CPLD在高频发射机控制系统中的应用

Application of CPLD in Local Control System Design of HF Transmitter

介绍一种基于CPLD的同步加速器高频发射机本地控制系统.高频发射机工作频率为0.5 MHz至4.2 MHz,工作模式为变谐波同步触发;本地控制系统采用了ALTERA公司的新一代内嵌FLASH存储器的MAXII系列CPLD芯片,结合抗干扰硬件设计,实现了发射机的自动开关机流程和连锁保护.该系统可靠地保护了发射机TH571B大功率电子管的正常工作,具有功耗低、稳定可靠的特点,并在加速器高频系统运行中取得了良好的效果.

A local control system of high frequency transmitter of synchronous accelerator whose transmitter operating frequency ranged from 0.5 MHz to 4.2 MHz was designed. The new low power cost Complex Programmable Logic Device（CPLD） embedded with flash memory was adopted in this local control system. This control system is successfully implemented in the work flow and interlock of high frequency transmitter, which guarantees high power vacuum tube TH571 B to work reliably and stably. The local control system is effectively applied in accelerator high frequency system.
