摘　　要：为了满足微细电化学加工的工艺需求与科研实验的要求,采用FPGA与STM32器件,设计了电化学微细加工双脉冲纳秒电源。测试实验表明,电源的脉宽、脉间、脉冲幅值电压、正/负脉冲个数调节方便,脉宽/脉间可以调至20ns以下,调节范围宽。通过RS232电源可以接收系统计算机的实时参数调整,能够有效满足微细电化学、微细电火花等多个领域与场合的生产与工艺实验需求。To meet the requirements of processing and scientific research and test of micro electrochemical machining,a dual pulse nanosecond power source is developed with FPGA and STM32 device.The performance tests indicate that it is easy to adjust the power source parameters such as pulse duration,pulse interval,the number of positive pulse,negative pulse,duty cycle,and voltage.Pulse duration and pulse interval can be adjusted with a wide range,even less than 20 nanoseconds.The RS232 power source can be adjusted in real-time by the system computer,which can effectively meet the needs of production and process experiments in many machining,such as micro ECM,micro EDM and etc.
