摘　　要：叙述了基于PhilipsP89C662单片机的高压充电电源控制系统的研制过程。该系统将充电电压分压采样并转换成频率信号,经光纤隔离送入单片机转化后测出。应用可编程逻辑器件增加了系统的硬件灵活性、掉电保存和液晶显示功能;光纤隔离及屏蔽的抗干扰措施保证了控制系统工作的可靠。充电电源控制系统充电电压精度高、操作方便,已在现场稳定可靠运行。This paper presents the control system of the high power charge power supply using single-chip computer P89C662. The charging voltage is measured by single chip computer which processes the signal acquired by fiber transmission from high voltage. The reliability of the control system is ensured by using fiber and shield box. The charging power supply has the advantage of high charging voltage precision, convenient operation and its reliability has been proved through the operation.
