<p>PURPOSE: A DC voltage supply apparatus of an electric discharge machine is provided to improve the effectiveness of an electrical discharge machine by outputting standard output voltage regardless load change. CONSTITUTION: A DC voltage supply apparatus of an electric discharge machine comprises a DC voltage supply devices for first and second pulse power generating units(1,8) and first and second pulse power generating units(2,4). The DC voltage supply devices for a first pulse power generating unit supplies voltage(V1). The first pulse power generating unit uses the voltage from a DC voltage supply device for a first pulse power generating unit as a supply power. The first pulsed power supply generating unit applies first pulse power on a workpiece and a wire(3).</p> |
