    • Current flow controlling hybrid DC circuit breaker 

      Mokberdoran, Ataollah; Gomis Bellmunt, Oriol; Silva, Nuno; Carvalho, Adriano (2018-02)
      Article
      Open Access
      This paper proposes a new device by combining features of an interline dual H-bridge current flow controller with the core idea of a hybrid HVdc circuit breaker for meshed HVdc grid application. The proposed device can ...

    • On improving phase-shifted PWM for flying capacitor multilevel converters 

      Ghias, Amer M.Y.M.; Pou Félix, Josep; Capellá Frau, Gabriel José; Acuna, Pablo; Agelidis, Vassilios (2016-08-01)
      Article
      Restricted access - publisher's policy
      This letter proposes a phase-shifted pulse-width modulation (PS-PWM) technique for the flying capacitor (FC) multilevel converter that improves the quality of the line-to-line voltages. In traditional PS-PWM, the line-to-line ...

    • Voltage balancing method for the multilevel flying capacitor converter using phase-shifted PWM 

      Ghias, Amer M.Y.M.; Pou Félix, Josep; Ciobotaru, M.; Agelidis, Vassilios (2012)
      Conference report
      Restricted access - publisher's policy
      n flying capacitor (FC) converters, phase-shifted pulse-width modulation (PS-PWM) provides natural voltage balancing. However, for a practical application, a more robust balancing mechanism of maintaining the FC voltages ...
    • Voltage balancing of a five-level flying capacitor converter using optimum switching transitions 

      Ghias, Amer M.Y.M.; Pou Félix, Josep; Ciobotaru, M.; Agelidis, Vassilios (2012)
      Conference report
      Open Access
      The flying capacitor (FC) multilevel converter requires a capacitor voltage balancing mechanism for proper operation. This paper proposes a voltage balancing scheme for a five-level FC converter based on phase disposition ...
