ABSTRACT:
A power supply for performing arc-machining operation includes a primary rectifier connected to the commercial AC power source and an inverter coupled to the rectifier. A switching device is provided between the rectifier and the inverter. By controlling the power supplied from the rectifier to the inverter, the switching device prevents a large switching loss from occurring in the inverter.
