    • Solar electric ambulance van unfolding medical emergencies of rural Bangladesh 

      Tarek, R.; Anjum, Adiba; Hoque, Md Ashiqul; Azad, Akm M.M.Abdul Malek (© 2016 IEEE, 2016-10)
      Rickshaws are a key mode of transportation in Bangladesh. When it was changed to electrically-assisted ones, it achieved prevalence but was soon banned because of overconsumption of power from the national grid. In ...

    • Three phase one switch modular-boost/vienna power factor corrected (PFC) rectifier 

      Uddin, Mohammad Nasir; Abedin, Amina Hasan; Bashar, Khandaker Lubaba; Islam, Samia M.Naeemul; Choudhury, Mohammad Ali A.Shoukat (© 2017 IEEE, 2017-04-26)
      The power conversion circuit of a three phase Vienna or Modular-Boost switching power factor corrected (PFC) rectifier uses three controlled switches, eighteen diodes and two output split capacitors. Three PFC controller ...

    • Transient anode voltage modeling of IGBT and its base doping profile investigation 

      Das, Avijit; Md Ziaur Rahman, Khan (© 2015 Institute of Electrical and Electronics Engineers Inc., 2015-12)
      In many power converter applications, study of doping concentration in the carrier storage region of IGBT is considered desirable. This paper introduces an estimation technique for base doping concentration through ...

    • Transient anode voltage modeling of IGBT and its carrier lifetime dependence 

      Das, Avijit; Islam, Nazmul; Haq, Masud Ul; Khan, Ziaurrahman (© 2015 IEEE, 2015-11)
      This work presents a minority carrier lifetime estimation technique through investigation into transient anode voltage modeling of Non-punch Through (NPT) Insulated Gate Bipolar Transistor (IGBT). Parabolic approximation ...

    • Two switch three phase ĆUK regulated rectifier 

      Abedin, Amina Hasan; Choudhury, Mohammad Ali A.Shoukat (© 2016 IEEE, 2016-11-22)
      A three phase Vienna/Modular-Boost rectifier provides only boost voltage gain regulation using three single phase PFC controller to achieve power factor correction and input current waveform improvement. A Buck-Boost voltage ...
