摘　　要：针对CNC电火花加工机床,设计了一种基于单片机W78E58B和复杂可编程逻辑器件(CPLD)的新型嵌入式数控脉冲电源,该电源脉冲宽度和脉冲间隙数控可调,在软件中利用模糊控制算法实现对加工状态的闭环控制,试验证明间隙电压稳定可靠,系统高效节能。A new numerical control pulse power supply of CNC electric sparkle discharge machining tool was introduced in this paper. It based on MPU-W78E58B and CPLD. Pulse duration and pulse interval can be numerical controlled in this power supply. It realized machining state closed loop controlled because Fuzzy arithmetic used in software. Test proved voltage of tool interval is stabilization and machining system work in high efficiency.
