Claim Text:
1. A power supply comprising: a power controller configured to apply DC or pulsed DC power to a plasma processing chamber; an arc management portion arranged between the power controller and the plasma processing chamber, the arc management portion including a shunt switch, a diode, and a filter capacitor, the shunt switch and the capacitor being arranged in parallel and arranged between high and low voltage potentials, the diode is coupled to the low voltage potential in series between the shunt switch and filter capacitor and having a cathode of the diode coupled to the filter capacitor and an anode of the diode coupled to the shunt switch such that the capacitor charges during steady state operation and discharges in order to reverse a voltage across the plasma processing chamber when the shunt switch closes, the arc management portion further comprising a non-transitory, tangible computer readable storage medium, encoded with processor readable instructions to extinguish one or more arcs in the plasma processing chamber, the instructions including instructions for:
