Abstract

Micro-energy pulse power supply is required in order to manufacture workpiece with micro-nano meter precision in electrical discharging machining (EDM). The paper analyzes two kinds of typical pulse power supplies and their important elements. Afterwards, another one kind of new micro-energy pulse power supply is presented. The experiments and analysis have been done for the new power supply. Accordingly, some important circuits have been modified, for example, the discharging circuit and driving circuit for the metallic oxide semiconductor field effect transistor (MOSFET). The modification improves the performance of the new pulse power supply so that the pulse width of the new pulse power supply could be less than that of the typical pulse power supply for electrical discharging machining. The least pulse width is obtained. It is less than 60 nanoseconds and its least energy of single pulse is less than 10-6 joule. Subsequently, the pulse waveform is adjusted considering the impedance matching of the discharging circuit in order that the pulse waveform has no oscillation and no overshot. The adjusted pulse waveform is good to detect discharging status correctly and sensitively.
