Abstract: A power supply to provide welding or cutting power. The power supply may include an input rectifier to receive an AC input voltage from an input mains and output a rectified DC signal; a PFC/boost block to receive the rectified DC signal and output a boost DC signal having a predetermined voltage independent of the AC input voltage; an inverter to receive the boost DC signal, and output AC power to an output transformer; a PFC controller to control operation of the PFC/boost block; a control block to control operation of the inverter; an internal power supply to receive the rectified DC signal and output a first DC power signal to power the PFC controller, and output a second DC power signal to power the control block.

Abstract: A power supply to provide welding power. The power supply may include a first printed circuit board (PCB) disposed on a primary side of the power supply; a first set of components mounted on the first PCB; a second PCB disposed on a secondary side of the power supply; a second set of components mounted on the second PCB; a transformer stage coupled to the first PCB and to the second PCB, wherein the first PCB and the second PCB are independently detachable from the power supply.
