Development of aircraft electric starter-generator system based-on active rectification technology (2018)
Journal Article

More-electric aircraft (MEA) has become a dominant trend for modern aircraft. On-board MEA, many functions, which are conventionally driven by pneumatic and hydraulic power, are replaced with electrical subsystems. Starting aircraft engines with an e...

Sensorless control of dual-three phase PMSM based aircraft electric starter/generator system using model reference adaptive system method (2018)
Conference Proceeding

A preliminary study into turbofan performance with LP-HP power exchange (2018)
Conference Proceeding

Once an engine is designed, its Low Pressure (LP) and High Pressure (HP) shaft speeds are inevitably thermodynamically coupled which imposes certain operational constraints. These spools are not mechanically connected, however, in future more electri... Read More about A preliminary study into turbofan performance with LP-HP power exchange.

Analytical modelling and power density optimisation of a single phase dual active bridge for aircraft application (2018)
Conference Proceeding

A design procedure for the Dual Active Bridge (DAB) converter is presented, which aims to optimized power density and computational effort. When designing a DAB, the selection of circuit design parameters such as switching frequency, leakage inductan...

Flux control modulation for the dual active bridge DC/DC converter (2018)
Presentation / Conference

This paper introduces a novel modulation technique for the single phase Dual Active Bridge (DAB) in which the switching frequency and transformer flux are modulated to achieve improved power transfer characteristics and reduced converter losses. By a... Read More about Flux control modulation for the dual active bridge DC/DC converter.

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...

Generic functional modelling of multi-pulse auto-transformer rectifier units for more-electric aircraft applications (2018)
Journal Article

The Auto-Transformer Rectifier Unit (ATRU) is one preferred solution for high-power AC/DC power conversion in aircraft. This is mainly due to its simple structure, high reliability and reduced kVA ratings. Indeed, the ATRU has become a preferred AC/D...
