    This paper presents an efficiency analysis of a recently-published topology, the multilevel-active-clamped (MAC) topology. In order to assess the MAC topology, an efficiency comparison between a four-level MAC leg and a ...
  • Fault-tolerance capacity of the multilevel active clamped topology 

    Nicolás Apruzzese, Joan; Busquets Monge, Sergio; Bordonau Farrerons, José; Alepuz Menéndez, Salvador; Calle Prado, Alejandro (IEEE, 2011)
    Conference report
    Restricted access - publisher's policy
    Thanks to the inherent redundancy to generate the different output voltage levels, the multilevel active clamped (MAC) topology presents an important fault-tolerance ability which makes it interesting for several applications. ...
