摘　　要：为更好地满足电火花的加工要求,提出一种基于FPGA的电火花加工脉冲电源的实现。研究电火花加工脉冲电源的工作原理,脉冲电源的核心部件高频脉冲发生器采用IP软核实现,其输出信号的脉宽和脉间精细可调,能与上位机有效通信。该方法的有效性通过仿真和电路测试得到验证。In order to meet the requirements in electrical discharge machining（ EDM）,an implementation of EDM pulse power supply based on FPGA was presented. The working principle of EDM pulse power supply was discussed. The high-frequency pulse generator,implemented with soft intelligent property（ IP） core,played a very important role in the pulse power supply which could be effectively communicated with the upper computer. The pulse width and pulse interval of output signal could be adjusted. The good performance of the proposed method was verified by simulated and circuit testing.
