Abstract
A boosting circuit is used to boost the voltage output of a DC selding power supply to a higher voltage output adequate for powering a plasma cutting torch. The boosting circuit includes a first inductive stage including an inductor receiving energy from a DC welding power supply. The boosting circuit also includes a capacitive second stage receiving energy from the inductor in the first stage where the two stages together boost the output of the boosting circuit to a voltage output higher than that supplied by the welding power supply.
