    • Application of decoupling networks in deadbeat controller for high-frequency link inverter 

      Zainal, Salam, Dr.; Toh, Leong Soon; Mohd. Zulkifli, Ramli (The Institution of Engineers, Malaysia, 2006-09)
      Deadbeat is a control method that results in very fast dynamic response. However its application in power electronics converters is somewhat hindered because it is very sensitive towards parameter variations. In an attempt ...

    • Cycloconverter-type high frequency link inverter for photovoltaic application 

      Zainal, Salam, Prof. Dr.; Nge, Chee Lim; Toh, Leong Soon; Mohd. Zulkifli, Ramli (The Institution of Engineers, Malaysia, 2006-03)
      The abundance solar energy in this country has triggered the interest of researchers to develop local products to be used in the solar photovoltaic (PV) systems. Although the development of solar cell itself is somewhat ...

    • Derivation of switching angles of the cascaded multilevel voltage source inverter subjected to a new pulse width modulation scheme 

      Zainal, Salam, Dr.; Junaidi, Aziz (The Institution of Engineers, Malaysia, 2009-09)
      A new modulation scheme for a five-level cascaded multilevel inverter is proposed. Unlike other schemes, the proposed method is based on the symmetric regular sampling unipolar PWM with a single carrier and multiple ...

    • A hybrid active power filter connected to aphotovoltaic array 

      Zainal, Salam, Dr.; Tan, Perng Cheng; Awang, Jusoh (The Institution of Engineers, Malaysia, 2008-03)
      This paper presents a single-phase two-wire hybrid active power filter (APF) that is connected to photovoltaic (PV) array. The uniqueness of proposed scheme is the fact that it the combines the conventional APF with high-pass ...

    • Review of active power filter technologies 

      Zainal, Salam, Prof. Dr.; Tan, Perng Cheng; Awang, Jusoh, Dr. (The Institution of Engineers, Malaysia, 2007-06)
      Active power filters (APF), are increasingly used to mitigate harmonics in utility power lines. Compared to the more established method such as the static var compensator or passive filtering, APF are relatively new in ...
