摘　　要：设计了一种金属凝固过程用脉冲电源。该电源采用PIC16F877作为主控芯片,实现对窄脉冲电流幅值的检测,以及对电流脉冲幅值根据模糊PID算法进行闭环控制。使用结果表明:该电源的输出脉冲波形良好,电流幅值稳定,满足合金材料凝固过程的工艺要求且运行稳定可靠。A kind of pulse power supply was designed which uses in the metal solidification process . This power supply used PIC16F877 to take the master control chip realization to the narrow pulse electric current peak-to-peak value examination , carried on the closed-loop control to the electric current pulse peak-to-peak value basis fuzzy PID algorithm. The use result indicated, this power supply output pulse profile is good,and the electric current peak-to-peak value is stable. It satisfies the alloy material solidification process the technological requirement and movement stable reliable.
