摘　　要：针对现有凝壳炉用直流电源晶闸管导通的一致性不高,输出电流稳定性不好等问题,文中提出了一种使用DSP与CPLD相结合对电源进行控制的方案。该系统以DSP进行信号的调理,CPLD进行脉冲分配,两者分工明确。使用PLC对整个系统进行监控与保护,保障了系统运行的稳定性。最后的仿真与调试结果证明了设计的可行性。Aiming at the problems that the consistency of the DC power supply thyristor used in the existing shell furnace is not high,and the output current stability is not good,this paper proposes a scheme that uses DSP and CPLD to control the power supply.The system uses DSP for signal conditioning and CPLD for pulse distribution.The division of labor between the two is clear.The use of PLC to monitor and protect the entire system ensures the stability of the system operation.The final simulation and debugging results prove the feasibility of the design.
