A welding power supply is a device that provides or modulates an electric current to perform arc welding. [1] There are multiple arc welding processes ranging from Shielded Metal Arc Welding (SMAW) to inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW).
It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact. Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used.
Power modules are used for power conversion equipment such as industrial motor drives, embedded motor drives, uninterruptible power supplies, AC-DC power supplies and in welder power supplies. Power modules are also widely found in inverters for renewable energies as wind turbines, solar power panels, tidal power plants and electric vehicles (EVs).
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.
