  • Sputtering apparatus
    Patent number: 7244343
    Abstract: A sputtering apparatus is provided with a DC power supply 1, an inverter 2 that converts DC voltage to AC voltage, a matching circuit 10 that transforms the AC voltage, a rectifier 4 that converts the transformed AC voltage to direct current, and a sputtering load 6. The matching circuit 10 has a transformer 3 that transforms AC voltage from the inverter 2, inductance L provided in series with at least one of the primary winding 31 and secondary winding 32, and a condenser C provided in parallel with at least one of the primary winding 31 and secondary winding 32 through inductance L.
    Type: Grant

  • Discharge power supply apparatus
    Patent number: 6998791
    Abstract: This discharge power supply apparatus is for supplying a D.C. voltage to a discharge load 6 and discharging the same. The discharge power supply apparatus includes an inverter circuit 2 that converts D.C. voltage to A.C. voltage; a transformer 3 having a primary winding 3a to which the A.C. voltage output by the inverter circuit 2 is supplied and a secondary winding 3b; a full-wave rectifier circuit 4 that has a plurality of diodes 4A to 4D and rectifies the A.C. voltage generated by the secondary winding 3b; and a trigger capacitor 7 connected in parallel to a part of the diodes of the full-wave rectifier circuit 4.
