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 ...
Transient analysis of mechanically switched capacitor with damping network
(Universiti Malaysia Perlis (UniMAP), 2014)
Mechanically switched capacitor with damping network (MSCDN) is used as reactive
power compensation unit in the modern power systems. MSCDN stabilizes the voltage
and increases the transmission capacity to ensure the ...
Simulation of shunt capacitor switching transient
(Universiti Malaysia Perlis (UniMAP), 2014)
Energization of capacitor banks and shunt reactors has been recognized
as a possible source of malfunctions due to the known effect of Switching Transient.
Switching transient can produce unwanted high currents with ...
Simulation of single phase fuel cell powered transformerless multilevel inverter using H-Bridge cascade topology
(Universiti Malaysia Perlis (UniMAP), 2014)
In this thesis, a multilevel inverter is constructed using H-Bridge Cascaded circuit to obtain output voltage for three, five, seven and nine level. It is operated without
transformer to obtain a nominal voltage of240V. ...
Dynamic model of distribution network cell using system identification approach
(Universiti Malaysia Perlis (UniMAP), 2014)
The centralised generation is generally a passive network. The interconnection of
distributed generation (DG) to this centralised generation have changed this passive network perspective to become an active power network. ...
Controlled switching of high voltage shunt reactor
(Universiti Malaysia Perlis (UniMAP), 2014)
This thesis characterized models and investigations into switching transient phenomena related to the shunt reactors and for reactive power control in the transmission system. Reactor banks play an important role in ...
The effect of DC bias and noise on the performances of power transformer
(Universiti Malaysia Perlis (UniMAP), 2014)
Direct current can be found in a transformer’s winding as a result of imperfections in connected equipment such as power electronics devices used and also due to magnetic disturbances of the earth’s field as geomagnetically ...
Solar light emitting diode (LED) street lighting with automatic vehicle detection system
(Universiti Malaysia Perlis (UniMAP), 2014)
This thesis is about a development and fabrication of solar light emitting diode (LED) street lighting with an automatic vehicle detection system. Present available solar street lightings are operated based on the timer ...
RF harvester for DC supply
(Universiti Malaysia Perlis (UniMAP), 2014)
This project focuses on the design of 2GHz rectenna for harvesting RF signal. This
2GHz signal is from a 3G signal and ISM band that is easy to be found in town areas. The rectenna comprises an array of rectangular patch ...
Control system and design and transient analysis of a grid integrated wind turbine
(Universiti Malaysia Perlis (UniMAP), 2014)
Wind power is one of the most reliable and developed renewable energy source. The
share of wind power with respect to total installed power capacity is increasing
worldwide. It is now more significant that the researchers ...
