    • Capacitor coupled converter (C3) for high power DC conversion 

      Ehsani, Morteza; Bilgiç, Mehmet Oruç; Khan, S.; Laskai, L.; Jeong, Seung-Gi (IEEE, 1995)
      The bang-bang controlled capacitor coupled converter (C<sup>3</sup>) is described in this paper. Due to the converter's inherent commutating property, the C<sup>3</sup> can accommodate thyristors as well as high-power gate ...
    • Fuzzy logic based control of switched reluctance motor to reduce torque ripple 

      Derdiyok, A.; İnanç, N.; Özbulur, Veysel; Pastacı, Halit; Bilgiç, Mehmet Oruç (IEEE, 1997)
      This paper presents torque ripple reduction of a switched reluctance motor (SRM) by using a fuzzy speed controller. For this purpose, current control is applied with a fuzzy speed controller. The fuzzy controller adjusts ...
    • Inverse dual converter (IDC) for high power DC-DC applications 

      Ehsani, M.; Husain, I.; Bilgiç, Mehmet Oruç (IEEE, April 1993)
      A family of DC-DC converters suitable for high-power applications is introduced. The inverse dual converter (IDC) is capable of continuous voltage step-up or step-down control over a wide range of and without the need of ...
    • Magnetically inflatable SPS with energy storage capability 

      Ehsani, M.; Bilgiç, Mehmet Oruç; Patton, A. D.; Mitra, J. (IEEE, 1995)
      A new approach to superconductive magnetic energy storage (SMES) for solar power satellite (SPS) with inherent rigidity is introduced in this paper. The rigidity of this SMES originating from the electromagnetic forces ...
    • New architectures for space power systems 

      Ehsani, M.; Bilgiç, Mehmet Oruç; Patton, Alton D.; Mitra, J. (IEEE, 1995-08)
      Electric power generation and conditioning have experienced revolutionary development over the past two decades. Furthermore, new materials such as high energy magnets and high temperature superconductors are either available ...
    • Power converters as natural gyrators 

      Ehsani, Mehrdad; Husain, Iqbal; Bilgiç, Mehmet Oruç (IEEE, 1993-12)
      The authors investigate the open-loop gyrator behavior of a class of DC-DC converters that are characterized by double bridges. If the switching frequency of the double bridge converter is high enough with respect to its ...
