Abstract
A method of manufacturing a plurality of welding-type systems, and the systems, are disclosed. The power supplies are each suitable for at least one of a plurality of processes, and have “N” (an integer) power modules in parallel. Each power module produces a module output power, and has a maximum output power of at least Ppm. Each power module has a similar preregulator that receives any input voltage over a range of input voltages and/or power factor corrects the input, and they include a converter circuit connected to the preregulator. The number N is determined by determining a desired maximum system power Pd1 for a first particular system, and by dividing Ppm into Pd1. There can be two types of power modules, with different output power. The output circuit may include an inverter that inverts dc power, and/or a switched snubber. The preregulator may includes an SVT and/or an SCT circuit. A single user interface may be operatively connected to the power modules, and the output may be ac, dc, cc, and/or cv.
