Arcing Behaviour of a Potential High-temperature Superconductor (HTS) Circuit Breaker Arc Model

Ullah, A; Lie, T; Gunawardane, K; Nair, NKC (IEEE, 2018)

Circuit breaker is a vital and sophisticated part of protection accessories in power system. An arc model of a circuit breaker can determine the dynamic and static feature for arcing directed by a power circuit. The idea ...
Design of an Efficiency Improved Dual-Output DC-DC Converter Utilizing a Supercapacitor Circulation Technique

Subasinghage, K; Gunawardane, K; Lie, T; Kularatna, N (IEEE, 2016)

The Supercapacitor Assisted Low Dropout Regulator (SCALDO) is a novel approach to achieving high end-to-end efficiency (ETEE) in linear, step-down, DC-DC converters. This is a patented technique and it has been well ...
Mitigation of residual flux for high-temperature superconductor (HTS) transformer by controlled switching of HTS breaker arc model

Lie, T; Ullah, A; Gunawardane, K; Nair, NKC (IEEE, 2017)

AC circuit breaker's controlled switching is a popular method to reduce dielectric and thermal stresses during switching of transformers, transmission lines, reactor and shunt capacitors. The magnitude of inrush current ...
