Abstract:

A switching power supply to drive magnetrons for microwave heating has been designed, prototyped and tested. The magnetron has an rf power output of 6000 watts and requires a DC voltage of 7200 volts at a current of approximately 1.1 amps for a power input to the magnetron of 8000 watts. Six magnetrons are to be connected per railway tanker for heating the tankers at a railway terminus. The power supply has been designed for small size, efficiency and reliability. Current technology has been used. Insulated Gate Bipolar Transistors (IGBT) and power MOSFETs, both of moderately high curr

Abstract:

Demands for delivering high instantaneous power in a compressed form (pulse shape) have widely increased during recent decades. The flexible shapes with variable pulse specifications offered by pulsed power have made it a practical and effective supply method for an extensive range of applications. In particular, the release of basic subatomic particles (i.e. electron, proton and neutron) in an atom (ionization process) and the synthesizing of molecules to form ions or other molecules are among those reactions that necessitate large amount of instantaneous power.

Abstract:

Since their conception in 1999, CubeSats have come and gone a long way. The first few that went into space were more of a “proof of concept,” and were more focused on sending simple data and photographs back to Earth. Since then, vast improvements have been made by over 40 universities and private firms, and now CubeSats are beginning to look towards interplanetary travel. These small satellites could provide a cost effective means of exploring the galaxy, using off the shelf components and piggy-backing on other launch vehicles with more expensive payloads. However, CubeSats are traditionally

Increased awareness of the effects of atmospheric pollution has meant that electrostatic precipitators, which have been used since the early part of this century to separate particulate matter from process gas streams, are now required to achieve particulate collection efficiencies in excess of 99.7% for a number of processes. Increasingly stringent legislation concerning industrial particulate emissions has challenged the precipitation industry to consider how equipment can be improved to reduce, in particular, heavy metal and respirable size particulate discharges.

The growing demand for high voltage, compact pulsed power supplies has gained great attention. It requires power supplies with high power density, low profile and high efficiency. In this thesis, topologies and techniques are investigated to meet and exceed these challenges. Non-isolation type topologies have been used for this application. Due to the high voltage stress of the output, non-isolation topologies will suffer severe loss problems. Extremely low switching frequency will lead to massive magnetic volume. For non-isolation topologies, PWM converters can achieve soft switching to i

First, the system transfer function including parastic capacitance effect is derived to select the resonant component. Moreover, the proposed system can achieve zero voltage switching to reduce power loss even under pulsed output. In addition, the modified burst PWM control is combined with variable frequency control to eliminate the output voltage spike. Furthermore, the voltage feedback control is implement

However, since it has a short half-life, meaning that it deoxidizes into oxygen in a short time span, makes it impossible to be put in mass production and store in containers. Hence, for small scale applications like in domestic use, a miniaturized ozone generator would be very convenient. The dielectric barrier ozone generator is one of the quietest types among all discharge ozone generators. Therefore, the main purpose of this thesis is focused to design and implement
