Space Weather Prediction to Enhance the Reliability of the More Electric Aircraft (2018)
Conference Proceeding

Power devices manufacturers know that electronic devices are susceptible to radiation events. Galactic Cosmic Rays (GCR) coming from space can interact with the earth atmosphere, generating secondary particles (electrons, neutrons, protons) that can...

Novel core designs to miniaturise passive magnetic components (2018)
Conference Proceeding

Converter sizes are often dominated by passive magnetic components. Passive magnetic component sizes are in turn limited by electromagnetic saturation and thermal limits. This paper covers two modifications to the air gaps of tape wound amorphous mag... Read More about Novel core designs to miniaturise passive magnetic components.

An advanced modulation scheme emphasising neutral point ripple suppression using predictive control for three-level NPC converters in aircraft electric starter generator applications (2018)
Conference Proceeding

Electrical starter/generator (ESG) system is one of the key innovations of more-electric aircraft initiative. The ESG cranks the engine and accelerates it up to self-sustained speed using electric energy (starter mode) and then runs as a generator to...
