Abstract
A power circuit for a welding power supply includes a control circuit, a power conversion circuit, a filter circuit, and a supplemental power circuit. The control circuit is configured to provide control signals to the power conversion circuit. The power conversion circuit is configured to generate a welding power based on the control signals. The filter circuit is configured to filter the welding power and to provide the filtered welding power at a welding output. The supplemental power circuit is configured to provide a supplemental power, wherein the supplemental power circuit is coupled across the filter circuit such that the filter circuit filters the supplemental power.
