Abstract
A method of operating a welding wire feeder includes receiving an input power signal from a power source and converting the input power signal to a bus power signal on an internal bus at a first time with a boost converter. The method also includes detecting bus voltage and bus current of the bus power signal on the internal bus and converting the bus power signal to a welding output signal at a second time with a buck converter. The welding output signal is suitable for a controlled waveform welding process. The method also includes detecting output voltage and output current of the weld output, and reducing a voltage ripple on the internal bus based at least in part on the detected bus and output current and/or voltages.
