    Restricted access - publisher's policy
    The use of permanent magnet synchronous generators (PMSGs) with full-scale back-to-back converters is rising as a common option in wind power generation systems (WPGSs). An efficient grid integration of PMSG-WPGSs is ...
  • Multi-stroke positive cloud-to-ground lightning sharing the same channel observed with a VHF broadband interferometer 

    Urbani, Michele; Montañá Puig, Juan; Van der Velde, Oscar Arnoud; Sousa Arcanjo, Marcelo Augusto; López Trujillo, Jesús Alberto (2022-04-15)
    Article
    Open Access
    In the same lightning flash, whose usual duration is less than a second, there can be multiple negative cloud-to-ground strokes with different terminations or following a preexisting channel to the ground. In contrast, it ...
