摘　　要：设计一种以CPLD作为脉冲发生器的电火花加工脉冲电源。利用CPLD产生两种模式脉冲波形,即等电流脉宽模式和等电压脉宽模式,设计了脉冲发生单元和功率转换电路,并用该脉冲电源对钛合金进行加工试验。通过对比两种脉冲模式加工钛合金的效率,发现等电流脉宽模式加工钛合金效率较高。One kind of pulse power supply which uses CPLD as pulse generator in EDM is designed. By two modes of pulse wave from CPLD, i.e. the equal current pulse width mode and the equal voltage pulse width model are realized. The design of pulse generator unit and the power converter circuit are analyzed, and experiments of machining titanium alloy were carried out by this supply. Comparing two pulse modes in machining titanium alloy indicate that the efficiency in equal current pulse width mode is higher.
