Abstract
There is provided by this invention an apparatus and method of supplying to ignite a plasma wherein in the event of an arc a shunt switch is used to divert the power away from the plasma that is incorporated into an over-voltage protection circuit that controls the shunt switch to act as a boost switch when the arc is extinguished such that the stored inductor energy is used to boost the ignition voltage for reigniting the plasma if it is extinguished. When the arc is extinguished, the inductor current is diminished, and the plasma is ignited, then the switch Sis turned OFF and the inductor energy goes to the plasma and the power supply operates in its normal operating mode.
