Abstract
PURPOSE:To obtain a sharp pulse current providing a short pulse width and a high peak value by supplying a discharge current of capacitors by a pulse power supply to a discharge gap between an electrode and a workpiece through a saturable reactor. CONSTITUTION:An AC power supply is rectified by a rectifier 1, and capacitors 61, 62 are charged through a high frequency transformer 4, rectifier 5 and a high frequency pulse circuit 3 by high frequency switching a switch 2. The capacitor is discharged by turning on a switch 8, but allowing a discharge current to flow in saturable reactors 71, 72, because their saturation characteristic is set in such a manner as to saturate the reactor with the capacitor discharge current, the capacitors 61, 62 decrease a pulse width of their discharge current, allowing a steep pulse current, increasing the fluctuating characteristic, to flow in a discharge gap 9. Further by providing two or more capacitors, repeated frequency increases by each discharge. By the constitution thus obtained, safe and stable electric discharge machining can be continuously performed.
