An analogue controlled switch-mode power system for a CubeSat
(Cape Peninsula University of Technology, 2013)The power system is essentially one of the most critical subsystems to any satellite, without some form of power system a satellite would simply cease to function. The research within these pages investigates the areas ... -
Augmentation of a nano-satellite electronic power system using a field-programmable-gate-array.
(Cape Peninsula University of Technology, 2013)The CubeSat standard has various engineering challenges due to its small size and surface area. The challenge is to incorporate a large amount of technology into a form factor no bigger than 10cm3. This research project ... -
CubeSat mission design for characterising the dual auroral radar network (SuperDAN) field-of-view
(Cape Peninsula University of Technology, 2013)The French South African Institute of Technology (F’SATI) at the Cape Peninsula University of Technology (CPUT) began a program in Satellite Systems Engineering in 2009 and is developing its first satellites. The satellites ... -
Development and assessment of reduced order power system models
(Cape Peninsula University of Technology, 2013)The demand for electrical energy has kept on increasing, thus causing power systems to be more complex and bringing the challenging problems of electrical energy generation, transmission, stability, as well as storage to ... -
Development of a low energy cooling technology for a mobile satellite ground station
(Cape Peninsula University of Technology, 2013)The work presented in this thesis consists of the simulation of a cooling plant for a future mobile satellite ground station in order to minimize the effects of the thermal noise and to maintain comfort temperatures onboard ... -
Development of a multi-cell inverter topology for driving nonlinear piezoelectric load
(Cape Peninsula University of Technology, 2014)This report presents the design and development of a five cell multicell inverter for driving a piezoelectric load. The multicell inverter was chosen for this application as it became evident that it would be more suitable ... -
Development of a power distribution module for a nanosatellite
(Cape Peninsula University of Technology, 2013)The space environment is characterised by harsh radiation, extreme temperatures and vacuum. Electronics subsystems for satellite applications are designed to be fault tolerant and robust enough to survive this environment. ... -
Development of a remote wireless monitoring system for large farms
(Cape Peninsula University of Technology, 2012)This research project addresses the unique challenges of extensive farming in terms of monitoring and controlling remote equipment or events. Poorly maintained roads and escalating fuel costs increase difficulty of farming ... -
Development of an embedded system actuator node for intergration into an IEC 61850 based substation automation application
(Cape Peninsula University of Technology, 2012)The introduction of the IEC 61850 standard in substations for communication networks and systems by the International Electrotechnical Commission (IEC) in 2003 provided the possibility for communication between devices of ... -
Digital control of a class-D audio amplifier
(Cape Peninsula University of Technology, 2011)Modern technologies have led to extensive digital music reproduction and distribution. It is fitting then that digital audio be amplified directly from its source rather than being converted to an analogue waveform before ... -
Image compression system for a 3u cubesat
(Cape Peninsula University of Technology, 2013)Earth observation satellites utilise sensors or cameras to capture data or images that are relayed to the ground station(s). The ZACUBE-02 CubeSat currently in development at the French South African Institute of Technology ... -
Investigation of the application of IEC61850 standard in distribution busbar protection schemes
(Cape Peninsula University of Technology, 2013)Busbars are the most important components in the distribution networks. Faults on the busbar are uncommon, however an occurrence of a busbar fault can lead to a major loss of power. Busbars are the areas in a substation ... -
Measurement methodology investigating home entertainment consoles and comparison against energy star and harmonic standards
(Cape Peninsula University of Technology, 2012)People are spending more time being entertained at home now than ever before. It is currently common to find a home entertainment console containing an LCD or Plasma television, DVD player and surround sound amplifier in ... -
A performance study of a voltage-fed reluctance synchronous machine
(Cape Peninsula University of Technology, 2013)The reluctance synchronous machine (RSM) operates on the principle of magnetic reluctance, which is produced through a careful selection of rotor flux barriers and cut-outs. Magnetic reluctivity is the resistance to magnetic ... -
A practical investigation into the measurement of forces on the stator teeth of electrical machines
(Cape Peninsula University of Technology, 2013)Radial and peripheral displacement of stator teeth in electrical machines is known to be the cause of undesired vibration which leads to noise. This thesis serves to investigate the possibility of physically measuring the ... -
A superconducting quantum interference device (SQUID) magnetometer for nanosatellite space weather missions
(Cape Peninsula University of Technology, 2012)In order to effectively determine the occurrences of space weather anomalies in near Earth orbit, a highly sensitive space-grade magnetometer system is needed for measuring changes in the Earth’s magnetic field, which is ... -
Wireless transformer condition monitoring system
(Cape Peninsula University of Technology, 2013)Pole mounted transformers (PMT) in rural areas present an opportunity for local utilities to do current monitoring on these systems. These transformers are exposed to abnormal amounts of stress due to the vast power demand ...
