VRLA battery float charge : analysis and optimisation.
(University of Canterbury. Electrical and Electronic Engineering, 2003)
This thesis investigates the float charge operation of Valve Regulated Lead Acid (VRLA) batteries in standby power applications. While the telecommunication standby power system is the targeted application, the results are ...
Digital Control of a Series-Loaded Resonant Converter
(University of Canterbury. Electrical and Computer Engineering, 2006)
Primarily because of its low cost and ease of implementation, analogue control has been the dominant control strategy in modern switch-mode power supply designs. The 'on/off' nature of power switches is essentially ...
Multi-level voltage and current reinjection ac-dc conversion
(University of Canterbury, 2003)
This thesis describes a new concept of multi-level reinjection ac-dc conversion, its main purpose being a further reduction of the harmonic content, a solution of dynamic voltage balancing for direct series connected ...
Evanescent near-field optical lithography : overcoming the diffraction limit.
(University of Canterbury. Electrical and Electronic Engineering, 2001)
Concepts of optical resolution limits have been transformed in the past two decades with the development of near-field optical microscopy. Resolutions of λ/40 have been demonstrated by taking advantage of additional ...
