POWER-SOURCE DEVICE, JOINING SYSTEM, AND CONDUCTIVE PROCESSING METHOD

摘要

A power-source device for supplying output current to an electroconduction processing device for the electroconduction processing of a workpiece, wherein the power-source device is provided with: a first power source; a magnetic energy regeneration switch for receiving the electric current supplied from the first power source and converting the electric current to an output electric current; and a control unit for controlling the magnetic energy regeneration switch so as to include a first electric conduction frequency and a second electric conduction frequency in which the electric conduction frequencies of the output electric current differ from each other within one time period of electroconduction processing by the electroconduction processing device.
