Comparative study of switching strategies for cascaded H-bridge multilevel inverter
(Universiti Malaysia Perlis (UniMAP), 2014)
Multilevel inverters are capable of producing AC staircase output waveform without
bulky passive filter. Therefore, among different types of inverters the multilevel
inverters are gaining popularity for photovoltaic ...
Electrochemical anodization of aluminum at room temperature by electronically controlled direct current circuit
(Universiti Malaysia Perlis (UniMAP), 2014)
Anodic aluminum oxide (AAO) films have been investigated and used in numerous
products for more than 50 years. The morphologies of the AAO films can be classified into barrier-type and porous-type. Barrier-type films ...
Study on Photocatalytic mineralization of various azo dyes under solar light irradiation
(Universiti Malaysia Perlis (UniMAP), 2014)
Azo dyes represented by azo chromophores (-N=N-) are the largest class of dyes used in many industries especially textile industries. Other chemicals that mutagenic or toxic to the environment and human life will present ...
