This paper introduces a newly developed EDM pulse generator whose high open voltage for discharge is generated by induced electromotive force using a power supply of only 5 V. The pulse generator can generate short duration and high discharge current pulses. The rising time of discharge current pulses to 5 A can be made shorter than 50 ns with a pulse duration of 200 ns or shorter. The results proved that such discharge current pulse shapes increase material removal volume per discharge and that the higher boosting open voltage facilitates the machining of high resistivity materials.

感应升压电路产生电火花高速放电电流脉冲

本文介绍了一种新开发的 EDM 脉冲发生器，其放电高开路电压是由感应电动势产生的，仅使用 5 V 电源。脉冲发生器可以产生持续时间短的高放电电流脉冲。在脉冲持续时间为 200 ns 或更短的情况下，放电电流脉冲到 5 A 的上升时间可以缩短到 50 ns 以下。结果证明，这种放电电流脉冲形状增加了每次放电的材料去除量，并且更高的升压开路电压有利于高电阻率材料的加工。
