    • A comparative study of different optimization methods for resonance half-bridge converter 

      Salehi, Navid; Martínez García, Herminio; Velasco Quesada, Guillermo (2018-12-02)
      Article
      Open Access
      The LLC resonance half-bridge converter is one of the most popular DC-DC converters and could easily inspire researchers to design a high-efficiency and high-power-density converter. LLC resonance converters have diverse ...
    • A novel high step-up secondary side impedance source full-bridge converter 

      Salehi, Navid; Martínez García, Herminio; Velasco Quesada, Guillermo (International Centre for Numerical Methods in Engineering (CIMNE), 2018)
      Conference report
      Open Access
      In order to suppress the voltage stress of semiconductor devices, and solve the reverse recovery problem of diodes by decreasing the duty cycle of switches, impedance source converters could be consider as a solution. In ...
    • Modified cascaded Z-source high step-up boost converter 

      Salehi, Navid; Martínez García, Herminio; Velasco Quesada, Guillermo (2020-11-17)
      Article
      Open Access
      To improve the voltage gain of step-up converters, the cascaded technique is considered as a possible solution in this paper. By considering the concept of cascading two Z-source networks in a conventional boost converter, ...
