20090084768 | PLASMA ARC POWER SUPPLY AND CONTROL METHOD THEREFOR - A plasma arc power supply with a simple structure and its control method enable shifting from a pilot arc to a main arc. A plasma arc power supply used in a plasma arc apparatus that processes a workpiece by forming a pilot arc between a main electrode and a nozzle electrode and subsequently forming a main arc between the main electrode and the workpiece includes N direct current power supply units (N≧2) having negative terminals connected to the main electrode and positive terminals to the workpiece, and a switch between the fourth power supply unit and the workpiece. The fourth power supply unit is connected to cause the nozzle electrode to have an opposite polarity to the main electrode. When the switch is open, the fourth power supply unit supplies a small current between the main electrode and the nozzle electrode while forming a pilot arc between them. | 04-02-2009 |
20090129122 | POWER SUPPLY DEVICE FOR ARC APPARATUS - This power supply device for an arc apparatus includes: a three phase full wave rectification circuit in which a plurality of semiconductor switching elements are connected in inverse parallel with a plurality of rectification elements, and which rectifies a three phase AC power supply; an AC reactor which is connected to the three phase AC power supply and the three phase full wave rectification circuit; a smoothing capacitor which smoothes the output voltage of the three phase full wave rectification circuit; an inverter circuit which converts the output of the smoothing capacitor to high frequency AC; and a rectification circuit which rectifies the output of the inverter circuit and supplies the result to a load. Moreover, this power supply device for an arc apparatus also includes a control is circuit which performs switching control of the semiconductor switching elements, so that the phases of the input voltage and of the input current of the three phase AC power supply agree with one another. | 05-21-2009 |
