    Controlling the thermal losses in the semiconductors ~s well. as the Co~mon Mode Voltage (CMV), are important Issues In the design of power electronics converters for photovoltaic applications. At present time there are ...
  • Modeling and simulation of synchronous machine and its behaviour against voltage sags 

    Aguilar Gaván, Daniel; Luna Alloza, Álvaro; Rolán Blanco, Alejandro; Vázquez Guzmán, Gerardo; Acevedo, Gustavo (2009)
    Conference lecture
    Open Access
    This paper studies the effects of voltage sags (dips), both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). The vast majority of the electrical power generation systems in the world is consist ...
  • Modeling of a variable speed wind turbine with a permanent magnet synchronous generator 

    Rolán Blanco, Alejandro; Luna Alloza, Álvaro; Vázquez Guzmán, Gerardo; Aguilar Gaván, Daniel; Acevedo, Gustavo (2009)
    Conference lecture
    Open Access
    The aim of this work is to analyze a typical configuration of a Wind Turbine Generator System (WTGS) equipped with a Variable Speed Generator. Nowadays, doublyfed induction generators are being widely used on WTGS, although ...
