This paper proposes the design and implementation of a 15kW three-phase T-type inverter. Fuji Electric's new generation IGBT module (V series) using RB-IGBT technology is applied for the converter, due to its higher efficiency from conventional IGBTs to reduce switching losses on the semiconductors. Under full load conditions, the overall efficiency of the converter can reach over 98%. The control design and sine PWM modulation are implemented on a DSP kit named TMS320F3F28379D. In addition, the PWM is generated with the fundamental and third harmonics of a sin wave, allowing a modulation factor up to 1,154 compared to traditional PWM. The output voltage of 220V/50Hz with less than 2% of THD can be achieved at the minimum input DC voltage of 550V.

This paper proposes the development of the methodology to be carried out for the metal joining process through the GMAW welding process in the Fanuc LR Mate 200iD industrial robot. The parameters or properties were considered for the application to be as efficient as possible, such parameters as speed of application, characteristics of the filler material, gas to be used as welding protection. The GMAW welding process can be applied semiautomatically using a hand gun, in which the electrode is fed by a coil, or an automatic form that includes automated equipment or robots. The advantages and disadvantages of the GMAW welding process applied in a manual and automated way were commented. The mechanical properties of the materials to which said welding can be applied were investigated; The materials with which this type of welding can be worked are the high strength materials, which are used in the automotive industry, for the forming of sheet metal. To know the properties of the material, destructive tests were carried out on the test material to be used, as well as the mechanical properties of the welding.
