    • Bifurcation behaviour of the buck converter 

      Chiang, Ng Kok, Ir. Dr.; Mei Lin, Nadia Tan, Dr; Tien Tien, Michelle Tan, Dr (The Institution of Engineers, Malaysia (IEM), 2014-06)
      The bifurcation and chaos phenomena appeared in power system have become a focus subject at present. It has become apparent about a decade ago that power converters exhibit various types of non-linear behaviour which ...

    • CNTs/SnO2 and CNTs/MNo2 nanocomposites for the fabrication of the electrodes for supercapacitors 

      Ng, Kok Chiang, Ir. Dr.; Jewell, Daniel A. Dr. (The Institution of Engineers, Malaysia (IEM), 2012-09)
      The development of next generation high-energy and high-power aqueous supercapacitors is vital in an era when power demand has peaked. In terms of engineering related issues at the micro level, the major area urgently ...

    • Control of bifurcation behaviour of the buck converter via a resonant parametric perturbation circuit 

      Chiang, Ng Kok; Tien Tien, Michelle Tan; Mei Lin, Nadia Tan (The Institution of Engineers, Malaysia (IEM), 2015-07)
      Nonlinear circuits and systems research has been growing very quickly over the past two decades. Actively pursued in almost every branch of science and engineering, nonlinear systems theory has found wide applications in ...

    • Novel bimetallic tin-manganese oxides-carbon nanotube nanocomposite and their charge storage properties 

      Chiang, Ng Kok, Ir. Dr; Lim, Siew Shee, Ms.; Peng, Chuang, Dr (The Institution of Engineers, Malaysia (IEM), 2014-06)
      The synthesis of CNTs/(Sn+Mn)Ox nanocomposites were first attempted through combining the hydro-oxidation of SnCl2 to SnO2 and the reduction of KMnO4 to MnO2 onto CNTs in this work. The reducing presence of SnCl2 accelerated ...
