A supercapacitor based enhancement technique for stand-alone surge protection circuits
(IEEE, 2013)With the International Technology Roadmap for Semiconductors predicting below-25nm feature-size VLSIs, powered by DC power supplies of less than 1V, protection against transients has become mandatory for modern electronic ... -
Analysis and design aspects of a series power semiconductor array with digital waveform control capability for single phase ac voltage regulators and other applications
(Scientific Research Publishing, 2011)A series connected power semiconductor array, with digital control capability could be used for developing single phase AC regulators or other applications such as AC electronic loads. This technique together with an ... -
Design approaches to supercapacitor based surge resistant UPS techniques
(Institute of Electrical and Electronics Engineers., 2011)Time constants of supercapacitors are in the range of 100mS to tens of seconds compared to the time durations of power line transients, which are usually within a few hundred microseconds. Therefore supercapacitors should ... -
Design enhancements of the smart sediment particle for riverbed transport monitoring
(2009)This paper discusses new enhancements that are being made to the existing ‘Smart Sediment Particle’. The smart sediment particle has been designed and implemented to track its own 3-dimensional trajectory when placed in a ... -
Developing a monitoring system for Toyota Prius battery-packs for longer term performance issues
(IEEE, 2013)The Toyota Prius battery pack consists of 38 individual battery blades, each blade contains 6 NiMH cells in series. This means that each pack contains 228 NiMH cells. Given this number of individually manufactured cells ...

Field data collection for implementation of Supercapacitor Assisted LED Lighting (SCALED)
(The University of Waikato, 2018)With the increasing impact of global warming, climate change is becoming the biggest threat for all life on our planet. The conventional way of generating electricity from the burning of fossil fuels releases significant ... -
Supercapacitor assisted power converter for DC microgrid applications with self-contained DC-UPS capability
(University of Waikato, 2017)Nowadays, due to the advantages inherent in using renewable energy, renewable power generation is becoming established worldwide. Direct current (DC) microgrid systems, which have been proposed as alternatives for traditional ... -
NiMH battery forensics: Instrumentation, modelling and prognostics for identifying failure
(University of Waikato, 2016)Battery forensics is a growing research field that is becoming increasingly important with the introduction of hybrid-electric and electric vehicles. The need to correctly diagnose battery condition and predict signs of ... -
Supercapacitor-based linear converter for voltage regulator modules
(University of Waikato, 2016)This thesis investigates a linear converter technique suitable for microprocessor voltage regulator modules (VRMs). The original linear regulator is the patented supercapacitor assisted low-dropout regulator (SCALDO). A ... -
Design and implementation of an AC voltage regulator based on series power semiconductor array
(University of Waikato, 2014)This thesis describes the use of an array of power semiconductors (series transistor array) and a buck-boost transformer in the design and implementation of a single phase AC voltage regulator. The power semiconductor array ...
