    Abstract: Power supply apparatus includes a converter which converts a commercial AC voltage into a DC voltage. An inverter converts the DC voltage into a high frequency voltage. The high frequency voltage is voltage-transformed by a transformer, and then rectified and smoothed by a rectifier and a smoothing reactor into a DC voltage. This DC voltage is applied between a workpiece and a torch. A high frequency voltage generator generates a high frequency voltage and applies it to a primary winding of a coupling transformer. A boosted high frequency voltage is induced in a first secondary winding and applied between the workpiece and the torch, so that arcing is initiated. The coupling transformer includes a second secondary winding in which another high frequency voltage is induced. The high frequency voltage induced in the second secondary winding is converted into a DC voltage by a diode and a smoothing capacitor for application between the workpiece and the torch, so that the arcing is sustained.

The respective ones of the two output terminals are connected to a torch electrode of the arc-utilizing equipment and a workpiece. A bypass capacitor and a high-frequency voltage generator circuit are serially connected between the two output terminals. A control circuit controls the high-frequency voltage generator circuit and the inverter circuit. The bypass capacitor is connected directly between one of the two output terminals and the high-frequency voltage generator circuit.
