Optimization of switching losses and capacitor voltage ripple using model predictive control of a cascaded H-bridge multi-level StatCom (2012)
Journal Article
Townsend, C. D., Summers, T. J., Vodden, J. A., Watson, A. J., Betz, R. E., & Clare, J. C. (2013). Optimization of switching losses and capacitor voltage ripple using model predictive control of a cascaded H-bridge multi-level StatCom. IEEE Transactions on Power Electronics, 28(7), doi:10.1109/TPEL.2012.2219593

This paper further develops a Model Predictive Control (MPC) scheme which is able to exploit the large number of redundant switching states available in a multi-level H-bridge StatCom (H-StatCom). The new sections of the scheme provide optimised meth...

Study of mid-infrared laser action in chalcogenide rare earth doped glass with Dy3+, Pr3+ and Tb3+ (2012)
Journal Article
Sójka, L., Tang, Z., Zhu, H., Bereś-Pawlik, E., Furniss, D., Seddon, A. B., …Sujecki, S. (2012). Study of mid-infrared laser action in chalcogenide rare earth doped glass with Dy3+, Pr3+ and Tb3+. Optical Materials Express, 2(11), doi:10.1364/OME.2.001632

We present a study of chalcogenide glass fiber lasers doped with Dy3+, Pr3+ or Tb3+ that would operate in the mid-infrared wavelength range. A set of chalcogenide glass samples doped with different concentrations of rare earth ions is fabricated....

Space-vector-modulated three-level inverters with a single Z-source network (2012)
Journal Article
Effah, F. B., Wheeler, P., Clare, J. C., & Watson, A. J. (in press). Space-vector-modulated three-level inverters with a single Z-source network. IEEE Transactions on Power Electronics, 28(6), doi:10.1109/TPEL.2012.2219627

The Z-source inverter is a relatively recent converter topology that exhibits both voltage-buck and voltage-boost capability. The Z-source concept can be applied to all dc-to-ac, ac-to-dc, ac-to-ac, and dc-to-dc power conversion whether two-level or...

A user-centred approach to requirements elicitation in medical device development: a case study from an industry perspective (2012)
Journal Article
Martin, J. L., Clarke, D. J., Crowe, J. A., Morgan, S. P., & Murphy, E. (2012). A user-centred approach to requirements elicitation in medical device development: a case study from an industry perspective. Applied Ergonomics, 43(1), doi:10.1016/j.apergo.2011.05.002

The healthcare industry is dependent upon the provision of well designed medical devices. To achieve this it is recommended that user-centred design should begin early, and continue throughout device development. This is a challenge, particularly f...
