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 ... -
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 ...
