Fluorescent lamp has been a very successful source of light. Installed base of TL(Tube Linear) is huge; more than 60 percent of artificial light is being generated today by fluorescent tube. However in the past few years LED lighting technology has been rapidly developed. LED (Light emitting diode) is a new technology that has become more energy...

As the need for electrical power from sustainable energy sources is continually increasing, electrical power generation from wind turbines continues to grow. A common type of electrical generators used in wind turbines is the Doubly Fed Induction Generator. However, this type of generator suffers from reliability issues associated with slip...

With growing interest in sustainable forms of energy, the wind industry is growing rapidly. The Doubly Fed Induction Generator is the most popular choice for the drivetrain because it is cost effective. However, it suffers from reliability and maintenance issues due to the slip rings and brushes it requires. The Brushless Doubly Fed Induction...

The increasing global energy needs and the high integration of renewable energy generation have changed the requirements for the electricity grid. Countries are becoming unable to cover their energy demands with their own means and the need for power exchange between neighboring countries has increased. Consequently, power needs to be...

In recent years, high penetration of distributed generation (DG) driven by PV panels and heavy load insertion in the distribution network has led to frequent voltage fluctuations in the form of undervoltage and overvoltage. Voltage control using traditional voltage regulators are unable to cope with this situation as frequent tap changes reduce...

The thesis presents a detailed design of 1.5kW induction cooker capable of heating all types of metals employed in the everyday cooking vessels. The design is based on newly developed control approach for resonant LLC DC-DC converters by NXP Semiconductors. The approach reduces the close loop transfer function of resonant converter to first...

In this thesis the feasibility of using superconductors to generate a magnetic field in an actuator is studied. The first objective of the thesis is to determine the achievable magnetic fields with commercially available superconductors. Second a superconducting actuator and its cryostat are designed. Finally the superconducting actuator is...

The use of power electronics DC/DC converters in aircraft has increased due to the state-of-art converters developments. However, the volume, efficiency and mass of such converters are critical issues. Each component of the DC/DC converters contributes to the total mass of the system. By designing each component, optimized to have small volume,...

Variable speed drives can cause components of any frequency known as interharmonics. Large variable speed drives in the order of tens of megawatts can replace Gas Turbines in driving cooling compressors in a Liquefied Natural Gas Plant. The drives used in this application are among the largest drives that are built today. As a consequence the...

In this thesis the development of the state of health of Li-ion battery cells under possible real-life operating conditions in electric cars has been characterised. Furthermore, a practical circuit-based model for Li-ion cells has been developed that is capable of modelling the cell voltage behaviour under various operating conditions. The Li...

Contactless Power Transfer (CPT) is the process of transferring power between two or more physically unconnected electric circuits or devices by means of magnetic induction. The potential application of CPT can range from power transfer to low power home and office appliances to high power industrial systems. Medical, marine, transportation,...

High speed fault tolerant permanent magnet machines have strong asynchronous airgap harmonics, making them susceptible to rotor eddy-current losses. These losses can be reduced by using novel high resistivity materials like plastic bonded magnets and carbon fibre reinforced retaining sleeves. This is an entirely new concept, and little knowledge...

Studies performed in the last decade have shown that wave energy could contribute as much as 10% in the current world electricity demand, making the ocean one of the most underrated and unexploited renewable sources so far. Wave energy offers distinctive advantages compared to other renewable technologies, providing a constant and predictable...

The principle of Inductive Power Transfer (IPT) is very old but it is rarely used for transferring power from source to load via a medium. This is because normally the medium restricts the power transfer due to losses or the shielding effects. However, for low energy applications, an acceptable amount of power could be transferred from the...
