摘要： Charge accumulated in a capacitor is used to provide a processing current flow between a target and an electrode. When a diode is turned on, a first dc power supply is used to provide the processing current flow between the target and the electrode. In this state, after a lapse of a predetermined time, the current supply using the first dc power supply is stopped, and an induced electromotive voltage, induced by two floating reactors, is used to rapidly drop the processing current flowing between the target and the electrode, while charging the capacitor.

摘要： To provide an electric discharge device capable of performing an optimum process that achieves a high-quality process in a satisfactory quality of processing precision and the like. In an electric discharge device that processes a workpiece by electric discharge, a reserve electric-discharge pulse is applied by alternately switching between a positive polarity and a reverse polarity, and a current waveform shape of a main electric-discharge pulse is differentiated corresponding to a polarity of a reserve electric-discharge pulse, to a main electric-discharge pulse to be applied after detecting electric discharge following the reserve electric-discharge pulse. With this arrangement, a processing current shape can be optimized corresponding to an electric discharge characteristic, and thus a high-precision process can be performed.
