Comparison on performance of voltage sags miligation techniques
(Universiti Teknologi MARA (UiTM), 2009-06-03)
The increasing use of sophisticated electronics, high efficiency variable speed drive, and power electronic controller, power quality has become an increasing concern to utilities and customers. Voltage sags is the most ...
Investigation of rolling and hard direction of magnetic field distribution on Grain Oriented M5 electrical steel material
(Universiti Malaysia Perlis, 2009-10-11)
This paper describes the idea of the electrical machine design perspective whose aim is latter on to design and development of the copper and aluminum rotor for induction motors to improve the operational efficiency. The ...
Tracing reactive power flow and loss in electric power systems
(Regional Energy Resources Information Center (RERIC), Asian Institute of Technology (AIT), 2009-03)
This paper suggests a systematic method to trace the reactive power flow and loss named as Proportional Tree Method (PTM). From the power flow solution, the test system is modeled conceptually like a tree, where the reactive ...
Parameters calculation of 5 HP AC induction motor

Power losses on grain oriented and non-grain oriented materials using epstein test for electrical machine design
(ACTA Press, 2009-10-12)
Modeling and definition of procedures leading to a good estimation of power losses in electrical machines from materials test data still is a challenge. The materials used in this experiment are grain oriented (GO) and ...
State space averaging technique of power converter with digital PID controller
(Institute of Electrical and Electronics Engineering (IEEE), 2009-01-23)
This paper describes a digital Proportional-Integral-Derivative (PID) controller technique applied to the DC-DC buck converter. The converter is modelled using a state spaceaveraging technique. Due to the non-linear of the ...
Design and implementation of a DSP based digital controller for a DC-DC converter
(Institute of Electrical and Electronics Engineering (IEEE), 2009-12-28)
The design and Digital Signal Processor (DSP) based implementation of a digital controller are presented for the dc-dc converter. Starting with a dc-dc buck converter and a given set of performance specifications, a digital ...
The power quality impact of adjustable speed drives in industrial distribution system
(Universiti Malaysia Pahang (UMP), 2009-06-20)
Applications of adjustable speed drives
(ASDs) have benefited many industrial facilities.
The primary function function of any speed drive
is to control the speed of a motor. This control
technique can significantly ...
