    • A single phase buck-boost AC-AC converter with low input current THD and high input power factor 

      Abedin, Amina Hasan; Kabir, Ashfanoor N M Enamul; Ahmad, Estiak; Rahman, Dhrubo; Choudhury, Mohammad Ali A Shoukat (© 2011 Institute of Electrical and Electronics Engineers Inc., 2011)
      Two new topologies of Buck-Boost single-phase ac-ac conversion are proposed. In one of the circuits a bi-directional switch with a single buck-boost inductor is used, whereas, in the other circuit a bi-directional switch ...
    • A single phase SEPIC AC-DC converter with improved power factor and input current THD 

      Hossain, Mohammad Rubaiyat Tanvir; Abedin, Amina Hasan; Choudhury, Mohammad Ali A.Shoukat (© 2016 IEEE, 2017-02-13)
      A new topology of single-phase SEPIC (Single Ended Primary Inductor Converter) AC-DC converter with low input current THD and high input power factor is proposed. Instead of using a single phase rectifier followed by a ...
    • State space modeling of a BUCK converter and designing a controller 

      Ahmed, Shaik Raju; Noor, Nusrat Jahan; Mostafa, Sumaiya (BRAC Univeristy, 2017)
      Modeling is the mathematical representation of a circuit. For mathematical representation knowledge of state space modeling or state space representation is required. For state space representation, it is necessary to ...
    • Study on designing the feedback loop control of buck converter 

      Khan, Md. Abdul Mobin; Rahman, Asifur; Hoque, Md. Rezuanul (BRAC University, 2016)
      Direct current to direct current (DC-DC) converters are power electronics circuits that converts direct current (DC) voltage input from one level to another. DC-DC converters are also known as switching converters, switching ...
    • 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 ...
    • True three-phase bidirectional switch based AC-AC Buck-Boost converter topology 

      Tanvir Hossain, Mohammad Rubaiyat; Abedin, Amina Hasan; Choudhury, Mohammad Ali A Shoukat; Uddin, Mohammad Nasir (© 2013 IEEE Computer Society, 2013)
      A new three-phase true bidirectional switch is proposed in this paper. This switch consist of a unidirectional switch enclosed in two three phase diode bridges with bidirectional input and output terminals. A family of ...
    • 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 ...
