Title: Arc power supply device
Inventor: SAITO FUSAO
IPC: G21B1/11
Filed: 1991-12-26
Abstract: PURPOSE:To achieve good economy and enhance the service efficiency by forming a circuitry with which the capacities of a transformer for power supply to arcs, a rectifier, a smoothing capacitor, etc., can be decided not with the arc ignition voltage but with the arc discharge voltage. CONSTITUTION:When a semiconductor switch 4 is in put-off state, a capacitor 7 is charged through a smoothing capacitor 3 and a circulating flow resistance 8, and if the switch 4 is put on at completion of this charging, the capacitor 7 makes discharging through the switch 4 and a reactor 6. This leads to occurrence of a resonance of the capacitor 7 and reactor 6, and the polarity of the capacitor 7 is inverted to be willing to invert the current, which is however blocked by the switch 4. Because the polarity of the voltage of capacitor 7 is identical to the polarity of the smoothing capacitor 3, a voltage approx. twice as large as the supply voltage stored in the smoothing capacitor 3 is impressed on the ion source 5. Accordingly the capacities of transformer 1, rectifier 2, capacitor 3, etc., are decided with the arc discharge voltage, which permits accomplishing a device with good economy and high service efficiency.
