System and method for controlling multiple processes in a welding-type power source using a refined controller architecture

An welding-type power source comprising:

• a power conditioner configured to condition an AC power;
• a first rectifier configured to convert the AC power to DC power;
• an inverter having a plurality of switches configured to receive the DC power from the rectifier and convert the DC power to inverted AC power;
• a second rectifier configured to convert the inverted AC power to a DC welding-type power to drive a welding-type process;
• and
• an FPGA-based processor having a first functional module that controls operation of the power conditioner, a second functional module that controls operation of the inverter, a third functional module that controls the welding-type process, and a port map linking at least two of the first, second, and third functional modules.

A welding-type device comprising:

• a power input configured to receive AC power;
• a first rectifier configured to convert the AC power to DC power;
• an inverter configured to receive the DC power from the rectifier and convert the DC power to inverted AC power;
• a second rectifier configured to receive the inverted AC power from the inverter and convert the inverted AC power to a welding-type power;
• at least one of a power conditioner and another inverter;
• and
• an FPGA-based processor having first and second decoupled functional modules having different word lengths, wherein the first and second decoupled functional modules are linked together by a port map, wherein the first decoupled functional module controls operation of the inverter, and wherein the second functional module controls one of the power conditioner and the another inverter.
