An hybrid welding module is disclosed. Such hybrid welding module includes a welding input switch (108), an energy storage input switch (110), an energy storage output switching circuit (112), and a control circuit (118). The welding input switch (108) receives welding-type input power and selectively outputs the welding-type input power to a weld circuit as first welding-type output power. The energy storage input switch (110) receives the welding-type input power and selectively conducts the welding-type input power to an energy storage device (120). The energy storage output switching circuit (112) converts energy output by the energy storage device (120) to second welding-type power and outputs the second welding-type power to the weld circuit. The control circuit (118) enables charging of the energy storage device (120) by controlling the energy storage input switch (110) to output the welding-type input power to the energy storage device (120), selectively controls the welding input switch (108) to output the welding-type input power to the weld circuit, determines a commanded total welding-type current, monitors a first welding-type current through the welding input switch (108), monitors a second welding-type current output by the energy storage output switching circuit (112), and controls the energy storage output switching circuit (112) to output the second welding-type power for combination with the first welding-type output power based on the commanded total welding-type current, the first welding-type current, and the second welding-type current.
