Implementation aspects of a new linear regulator topology based on low frequency supercapacitor circulation
Kankanamge, Kosala; Kularatna, Nihal (IEEE, 2012)Point of load (POL) powering concepts are used in modern portable products where low dropout regulators (LDO) are mixed with switching regulators. However, LDOs are efficient only when the input to output differential ... -
Laplace transform-based theoretical foundations and experimental validation: low-frequency supercapacitor circulation for efficiency improvements in linear regulators
Kankanamge, Kosala; Kularatna, Nihal; Steyn-Ross, D. Alistair (Institution of Engineering and Technology, 2012)Supercapacitor circulation techniques can be used to improve the end-to-end efficiency of linear regulators based on commercial low drop-out regulators (LDO). In this approach, one or more supercapacitors are used in series ... -
A low frequency supercapacitor circulation technique to improve the efficiency of linear regulators based on LDO ICs
Kularatna, Nihal; Fernando, Jayathu; Kankanamge, Kosala; Zhang, Xu (IEEE, 2011)Linear regulators have output specifications far superior to switch-mode techniques, except for the overall efficiency. This efficiency limitation can be overcome by applying a very low frequency supercapacitor circulation ... -
Supercapacitor assisted LDO (SCALDO) techniquean extra low frequency design approach to high efficiency DC-DC converters and how it compares with the classical switched capacitor converters
Kankanamge, Kosala; Kulatana, Nihal (IEEE, 2013)Supercapacitor assisted low dropout regulators (SCALDO) were proposed as an alternative design approach to DC-DC converters, where the supercapacitor circulation frequency (switching frequency) is in the order of few Hz ... -
Very low frequency supercapacitor techniques to improve the end-to-end efficiency of DC-DC converters based on commercial off the shelf LDOs
Kularatna, Nihal; Fernando, Jayathu; Kankanamge, Kosala; Tilakaratna, L. (IEEE, 2010)Given the advantages of linear regulator techniques, low dropout regulator ICs are frequently used in portable consumer electronics. Only disadvantage in linear regulators, low efficiency, can be overcome by a very low ...
