SYSTEM AND METHOD FOR CONTROLLING MULTIPLE PROCESSES IN A WELDING-TYPE POWER SOURCE USING A REFINED CONTROLLER ARCHITECTURE

摘要

A system and method for operating an welding-based power source includes an welding-type power source (42) includes a power conditioner (12) configured to receive power from a power source (24) and condition the power to have characteristics within a predefined set of thresholds and an inverter (16) configured to receive the conditioned power from the power conditioner and convert the conditioned power to AC power. The welding- type power source also includes a rectifier (18) configured to convert the AC power to DC welding-typ power to drive a welding- type process and a processor (44) segregated into at least two functional modules. The processor may be a field programmable gate array (FPGA) based processor. A first functional module is configured to control the power conditioner to condition the power to have characteristics within the predefined set of thresholds and a second functional module is configured to control the inverter to convert the conditioned power to AC power.
