Abstract

PURPOSE:To simplify the structure by making arrangement such that when the discharging capacitor terminal voltage has exceeded a reference level during charging of the said capacitor, the gate circuit is closed to shut off the pulse to clamp the discharging capacitor terminal voltage at a predetermined value. CONSTITUTION:In a condition where space discharge between wire 5 and workpiece 6 has terminated and the charges accumulated in the discharging capacitor 2 have been lost, the switching transistor 4 is opened intermittently by the pulses from a pulse generator 13 to charge the capacitor 2 by a DC power source 1. When charging reaches a predetermined level, the comparator 11 closes the gate circuit 12 and the transistor 4 to inhibit further charging of the discharging capacitor 2.
