Diseño y Construcción de un Inversor Multinivel
Revista Politécnica, 2014 Muchos de los inversores comerciales usan modulación de dos o tres niveles y se utilizan filtros de salida para obtener una forma de onda aproximada a la sinusoidal. El presente trabajo muestra los resultados de la construcción de un inversor multinivel (81 niveles) en base a inversores de tres niveles conectados mediante transformadores en serie.

Advanced Engineering Materials, EarlyView.Excellent combinations of strength and impact toughness are obtained in a bilayer composite of high‐strength carbide‐free bainitic (CFB) steel and high‐ductility twinning‐induced plasticity (TWIP) steel. The composite absorbs energy at small strains when the notch is placed on the TWIP side and at high strains when the notch is placed on the CFB side ...

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects
Advanced Engineering Materials, EarlyView.Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...
