Reliable integration of a high performance multi-chip half-bridge SiC power module
Presentation / Conference Contribution
Mouawad, B., Li, J., Castellazzi, A., & Johnson, C. M. Reliable integration of a high performance multi-chip half-bridge SiC power module. Presented at 6th Electronics System-Integration Technology Conference (ESTC’16)

Silicon carbide (SiC) devices have been adopted to push the boundaries further in terms of power density, conversion efficiency, switching speed or thermal capability. To have the benefit of such semiconductors, new packaging should be developed to m... Read More about Reliable integration of a high performance multi-chip half-bridge SiC power module.

Presentation / Conference Contribution
Yoeh, S. S., Yang, T., Tarisciotti, L., Hill, C. I., & Bozhko, S. More electric aircraft starter-generator system with utilization of hybrid modulated model predictive control. Presented at International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles and the International Transportation Electrification Conference (ESARS ITEC 2016)

The current trend for future aircraft is the adoption of the More Electric Aircraft (MEA) concept. The electrical based starter-generator (S/G) system is one of the core ideas from the MEA concept. The PI based control scheme has been investigated in... Read More about More electric aircraft starter-generator system with utilization of hybrid modulated model predictive control.

Nonlinear aircraft engine model for future integrated power center development
Presentation / Conference Contribution
Enalou, H., Rashed, M., Kulsangcharoen, P., Hill, C. I., & Bozhko, S. Nonlinear aircraft engine model for future integrated power center development. Presented at ESARS Itec 2016

Aircraft engines, the prime source of on-board power, play a vital role within the electrical power generation system. In literature these are considerably simplified to rudimentary engine speed. In this paper, a nonlinear zero-dimension (0-D) order... Read More about Nonlinear aircraft engine model for future integrated power center development.

Threshold preservation of PT-resonant structures in realistic-dispersive medium
Presentation / Conference Contribution
Phang, S., Vukovic, A., Creagh, S. C., Benson, T. M., Sewell, P., & Gradoni, G. Threshold preservation of PT-resonant structures in realistic-dispersive medium. Presented at Optical Wave and Waveguide Theory and Numerical Modelling Workshop (OWTNM 2015)

The impact of material dispersion in the performance of parity-time (PT) symmetric coupled microresonators is studied. The eigenfrequencies of the coupled PT-system are analysed for different dispersion parameter. We show that realistic dispersion pr...

Intergenerational interpretation of the Internet of Things
Book
Brown, M., Coughlan, T., Lawson, G., Mortier, R., Houghton, R., & Goulden, M. Intergenerational interpretation of the Internet of Things. Horizon Digital Economy Reseearch Institute. Manuscript submitted for publication

This report investigates how different generations within a household interpret individual members’ data generated by the Internet of Things (IoT). Adopting a mixed methods approach, we are interested in interpretations of the IoT by teenagers, thei... Read More about Intergenerational interpretation of the Internet of Things.

Parity-Time coupled microresonators: Kramers-Kronig limitation
Presentation / Conference Contribution
Phang, S., Vukovic, A., Creagh, S. C., Sewell, P., Gradoni, G., & Benson, T. M. Parity-Time coupled microresonators: Kramers-Kronig limitation. Presented at CLEO®/Europe-EQEC 2015

In this talk, we use a KKE argument to show that the presence of dispersion alters the eigen-frequencies of coupled PT coupled microresonators, so that their eigen-frequencies are no longer complex conjugates after the EP.

Coupled parity-time symmetric cavities: results from transmission line modelling simulations
Presentation / Conference Contribution
Phang, S., Vukovic, A., Creagh, S., Sewell, P. D., Gradoni, G., & Benson, T. M. Coupled parity-time symmetric cavities: results from transmission line modelling simulations. Presented at 17th International Conference on Transparent Optical Networks ICTON 2015

This paper studies the impact of a dispersive gain/loss material model on Parity-Time (PT) coupled microresonator cavity structures using the time-domain Transmission-Line Modelling method. A modal analysis is also performed to compare the modal comp... Read More about Coupled parity-time symmetric cavities: results from transmission line modelling simulations.

Presentation / Conference Contribution
Klumpner, C., Lee, M. Y., Pitic, C., Wheeler, P., & Zanchetta, P. A new three-level indirect matrix converter with reduced number of switches. Presented at IEEE-IAS 2007 Annual Meeting

Matrix converters are sine wave in/out forced commutated single-stage AC/AC direct frequency changers using a single bi-directional switch to connect any input to any output. Indirect two-stage matrix converters provide similar input and output perfo... Read More about A new three-level indirect matrix converter with reduced number of switches.
