摘　　要：根据低速走丝线切割机床对脉冲电源的要求,利用单片机和高集成度的可编程逻辑器件(CPLD)的优势,实现了脉宽和脉间连续可调,且频率可达到ns级的脉冲基准信号。This article according to pulse power＇s request of LSWEDM, has used singlechip and the programmable logical component（CPLD） superiority, realizes that the pulse width and clearance adjust continuously, at the same time, the high frequency pulse standard signal can achieve the ns level.

关 键 词：单片机 可编程逻辑器件 脉冲基准信号
