      This paper describes a control design methodology based on output impedance analysis for multiphase synchronous buck converters. This design leads to an optimal output voltage transient response. Two design alternatives ...
    • Controlador de histéresis de bajo coste para convertidos buck síncrono multifase 

      Borrell Sanz, Angel (Universitat Politècnica de Catalunya, 2012-07-12)
      Doctoral thesis
      Open Access
      The multiphase synchronous buck converter is universally used today for powering low voltage, high current and high slew-rate loads, such as CPUs and other high performance digital ICs. This converter demands control ...
    • Reactive power control for distributed generation power plants to comply with voltage limits during grid faults 

      Camacho Santiago, Antonio; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Guzmán Solà, Ramon; Borrell Sanz, Angel (2014-01-20)
      Article
      Open Access
      Grid faults are one of the most severe problems for network operation. Distributed generation power plants can help to mitigate the adverse effects of these perturbations by injecting reactive power during the sag and the ...
