Analysis on Supercapacitor Assisted Low Dropout (SCALDO) Regulators
(University of Waikato, 2014)State-of-the-art electronic systems employ three fundamental techniques for DC-DC converters: (a) switch-mode power supplies (SMPS); (b) linear power supplies; (c) switched capacitor (charge pump) converters. In practical ... -
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 of SCALDO based high-current DC power supply
(The University of Waikato, 2021)Supercapacitor assisted (SCA) techniques are primarily based on supercapacitors having in the order of one million times more capacitance, together with one to two orders of magnitude smaller equivalent series resistance ... -
Development of a Power Factor Corrected High Current Supercapacitor Charger for a Surge Resistant UPS
(University of Waikato, 2012)The Uninterrupted Power Supplies (UPSs) provide short term power back up to electrical loads when the mains power fail. Usually UPSs employ battery packs as the energy storage device. However the limitations of battery ... -
Permeance based modelling, design and optimization of supercapacitor assisted surge absorber (SCASA)
(The University of Waikato, 2021)Supercapacitor assisted (SCA) techniques are a unique set of circuit topologies designed to fulfil power conversion and protection tasks by circumventing the energy losses normally associated with RC based circuits. With ... -
Supercapacitor assisted low dropout regulators (SCALDO) with reduced switches: A new approach to high efficiency VRM designs
(IEEE, 2013)Supercapacitor assisted low dropout (SCALDO) regulator is a new approach to develop high efficiency DC-DC converters with supercapacitors used for energy recovery. One limitation in these topologies is that in some ... -
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 ...
