      Digital control of power converters has been an area of considerable research interest in recent times. One of the problems which arises in these systems is that of the limit cycle oscillations that occur due to ...
    • Counting configurations of limit cycles and centers 

      Gasull, Armengol; Guillamon Grabolosa, Antoni; Mañosa Fernández, Víctor (2023-04-10)
      Report de recerca

    • Delay effects on the limit cycling behavior in resonant inverters with state feedback 

      Benadero García-Morato, Luis; El Aroudi, Abdelali; Ponce, Enrique (2019-10-01)
      Article
      Accés restringit per política de l'editorial
      Bifurcations of limit cycles in an H-bridge LC resonant inverter are reexamined taking into account a time delay in the switching transition. The analysis is accomplished by means of a model of the inverter that compresses, ...
    • In-depth analysis of smooth and nonsmooth bifurcations for an open-loop boost converter feeding constant power loads in discontinuous conduction mode

      Accés restringit per política de l'editorial
      In this paper, instabilities and bifurcation behavior in a DC–DC digitally controlled voltagemode synchronous buck converter (SBC) are studied. The bifurcation diagram of the system under a proportional-integral (PI) ...
    • Persistence of periodic traveling waves and Abelian integrals 

      Gasull Embid, Armengol; Geyer, Anna; Mañosa Fernández, Víctor (2021-03-10)
      Report de recerca
      Accés obert
      It is well known that the existence of traveling wave solutions (TWS) for many partial differential equations (PDE) is a consequence of the fact that an associated planar ordinary differential equation (ODE) has certain ...
